Preferences pop-up too long for screen - can't click ok or cancel - HELP

I would suggest resetting your preferences which brings the program back to its "Factory settings". Hopefully a "fresh" InDesign will restore proper performance for you.

To do so on a Mac:

The User Library folder in which InDesign’s preferences are stored is hidden by default on most Macintoshes. To access it make sure that InDesign is closed and click on the desktop to launch a Finder Window (Command-N). With this window in column view follow the path User>Home folder (it’s the folder with an icon that looks like a house—it may have the user’s name rather than “Home”) and click on the Home folder. With the Option Key pressed choose Library from the Finder Go Menu. “Library” will now appear within the Home folder. Within the Library folder find the folder called Preferences and within it find the folder called “Adobe InDesign” and the file called “com.adobe.InDesign.plist” and delete both that folder and that file. When InDesign is next launched it will create new preference files and the program will be restored to its defaults.

The advantage of manually deleting preference files in this manner is that after you’ve reset up the program (make sure that no document window is open) to your liking, you can create copies of your personalized “mint” preference files (make sure that you quit the program before copying them—that finalizes your customization) and use them in the future to replace any corrupt versions you may need to delete.

Hello @hollypitches,

Check you Display settings.....

System Preferences > Displays > Display

when view settings are "Scaled" and set to Larger Text you'll get a message "When using this scaled resolution, some applications may not fit entirely on screen"...It's just a guess for your case.

Regards,

Mike

I don't experience that problem on my Mac. Can you give us more information: Please tell us what operating system (exactly) you're running. Please tell us (exactly) what InDesign version you're using. What monitor resolution is set?

On a Mac, you can cancel by pressing Cmd + [period]. You choose OK by pressing the < Return> key.
