There are still many bugs left in the split window mode. For instance, InDesign crashes a lot copy-pasting between the two sides of the split window view. Beside this, InDesign has some difficulties remembering the page number displayed in the page number area below each one of the two sides of the window of the same document. Really annoying. This affects the last version (19.0.1) but this is a bug running for several years.

We have released InDesign CC2019.0.2 with lot of bug fixes. If you are not on 14.0.2.324 then I would recommend you to upgrade to latest version as it is more robust.

If you still face this issue even after updating, please provide more information to santalwa@adobe.com –
• Reproducible Steps – What were you doing when you encountered the issue in InDesign?
• Error snapshot or video recording of the issue?
• Is(Are) the issue related to a specific document(s)/asset(s)? If Yes, Can you please provide the document(s)/asset(s)?

I am running Adobe InDesign CC 14.0.1.x64 on Windows 7 with latest updates (i.e., the most popular platform in the world).

1. Open the document (see attached).
2. Split the window (Window > Arrange > Split Window).
3. Scroll the left window to show page 2, with the Table of Contents.
4. Scroll the right window to show e.g. page 3, with the cursor in the middle of the page.
5. With the Type tool active, click the Enter key.
6. InDesign correctly inserts a new paragraph, with the left window remaining unchanged.
7. Alt-Tab out of InDesign.
8. Alt-Tab back into InDesign. The Type tool should still be active, with the cursor in the right window.
9. Click the Enter key again.
Expected Behavior: Same as Step 6, including that the left window is unchanged.
Actual Behavior: Same as Step 6 PLUS the left window scrolls.

Sure, after coming back in with Alt-Tab, I can click the left window before making changes in the right window, but that's a pane.
