CMD+O (Open File) STILL Doesn't Work in 15.0.3 on first launching InDesign
This still hasn't been fixed!! When first opening InDesign 15.0.3 CMD+O just gives a 'dead key' beep, and it doesn't bring up the 'Open File' dialog. You must use the MENU to open the first file. After you have opened a file from the MENU, the CMD+O will then work. PLEASE FIX, for us long-time users this is painfully annoying! I have reported this in previous releases.
Thanks for reporting the issue. We are reviewing it
It seems to work OK for me on a Mac running Mojave with v15.0.3
