Excel filter rejects custom Cell Range for 26-column sheets (.xlsx-only)

Steps to reproduce the issues:
1. Create a new document.
2. Select File > Place, check Show Import Options, select attached Columns_26.xlsx file.
3. Note nonstandard default Cell Range: A1:A@10 (should be A1:Z10).
4. Enter custom (valid) Cell Range "A1:E5"

Expected result:
No error and a table containing cells A1 through E5.

Actual result:
Error message, "You have not entered a valid 'Cell Range'. (See attached screenshot.)

This error is given for any sheet whose right-most column is a multiple of 26 (so Z, AZ, BZ, etc.). Place the attached Columns_52.xlsx with range "A1:E5", for example.

Adding/removing a column (attached Columns_27.xlsx file) avoids the error.

Versions of Adobe InDesign:
CS6 through CC 2018.0, Windows and macOS

Test files and screenshot of error attached.

When placing an Arabic weight statement (e.g. "13g") followed by a tab and a percentage (e.g. "19%"), the weight declaration ("g" or "mg") moves to the percentage when exporting to pdf. Only when setting PDFX/1a:2001 is selected the output is correct. But this setting removes all layers and flattens transparencies so it's not very useful.
A workaround is to place a space after the tab (so on the left side since this is a right to left language).
See screen shot in attachment. On top = InDesign file, bottom = pdf created from this file using PDFX/4. The top line in the Indesign file has no space after the tab, resulting in a wrong placement of the "غ" (= Arabic "g") as marked red in the screen shot.

My InDesign opens the destination folder when exporting PDF-files. In my work I export files daily and I have to export them separately. So when I do this, after the export has completed successfully, the destination folder opens up automatically, which is very annoying. I can't seem to find any place, where I can turn this off. I can only turn it ON, if I don't export separately.

1. brand new update CC 2019
2. Create a document with more than 2 pages. Export all the pages separately.
3. That it exports the pages separately into the destination folder without having the need to watch them in that folder (I use Bridge).
4. It opens the destination folder in a new folder window.

Cursor Direction when typing Arabic or other RTL languages. in Middle Eastern version ONLY.

1. All Middle Eastern versions (English يدعم العربية)

2. Type Arabic text. Place the cursor within text. Hold "Shift" key and click on right arrow key on the keyboard to select/highlight text. Cursor moves left and select next character on the left while clicking on right arrow.

3. To select a character to the left of the cursor, we should hold (Shift+left arrow) To select a character to the right of the cursor, we should hold (Shift+right arrow)

4. What actually is happening now and for over 20 years when we had Adobe PageMaker ME and Adobe Illustrator ME is the opposite cursor behavior to the what we're trying to select. We hold (Shift+right arrow) cursor will move and select text to the left, we hold (Shift+left arrow) cursor will move and select text to the right.

Adding Hunspell dictionaries breaks code-signing, and results in the whole of InDesign's spelling system being sand-boxed by OSX.

Steps to reproduce:

1. On High Sierra and InDesign CC, add a Hunspell dictionary, as detailed here: https://helpx.adobe.com/indesign/kb/add_cs_dictionaries.html

2. Spell-check any InDesign document using the new dictionary and spell-checking then becomes unusable, until InDesign is uninstalled then re-installed.

The following types of errors are produced in the console, showing that it's a code-signing issue, caused by dictionaries being installed within the Hunspell plugin bundle.

Can I suggest that there should be another place to install additional languages, outside the InDesign application.

The only way I can work with Latin and Ancient Greek languages currently is to use an El Capitan Mac, which does not have the sandboxing.

AMFI: Check-fix enabled for binary '/Applications/Adobe InDesign CC 2018/Resources/Dictionaries/LILO/Linguistics/Providers/Plugins2/AdobeHunspellPlugin.bundl e/Contents/MacOS/AdobeHunspellPlugin' with TeamID 'JQ525L2MZD', identifier 'com.adobe.adobehunspellplugin2': broken signature treated as unsigned without privileges. This workaround will not work for software built on or after 10.12.

We've been making a large catalogue pricelist for over 13 years using indesign.

We're now stuck on the 2017 (12.1.0) version.
We want to update it, but in the latest version, importing our pricelist from excel into a table, slows the whole thing down to an unworkable speed.

info:
the table is around 13000 rows by 10 columns. so not small.
it does import in the 2017 version. slow to import in both, but can use and work on after import in 2017 version.
2019, freezes when scroll used, and take 1-3 mins to unfreeze. Scroll again or do anything much else and freezes again.
I can see it's using 100% of 1 CPU core. And I know Indesign is built in a way that it can only use 1 CPU core! (please fix this!!!!)

Using Windows 10 Pro, high end computer (Ryzen 1800X, 32Gb RAM, NVMe SSD, 1080Ti)

Create an Excel file with 8000 rows of random data, place into InDesign with as unformatted table.

Use shift-click to create pages and thread the table to each page.

Try to scroll without InDesign freezing for 30 seconds. I can't.

I have tried:
- Cleaning preferences / logging on different username to have a fresh profile
- Using a different computer
- Turning off preflight
- Using fast display performance
- Change the composer away from world ready, trying single line instead of paragraph
- Turned off Type Contextual Controls

There is ONE thing that works: use InDesign 2015. Nothing after that, up to CC2019 / 14.0.2, is even remotely usable. I do this kind of work a lot and it's a shame the newer versions don't work for me.
