I am going insane witht this issue. InDesign menus won't stay open to allow me to click on anything, including window dropdowns. I've tried everything, resetting preferences, deleting all versions of indesign and reinstalling. I am unable to use the software at all for hours at a time, every day. What is going on?? Has anyone else found this issue? I use inDesign most of my working day so can't do anything.
Is there any third party software recently installed? Any anti-virus or anything else added/updated in the last few days?
How did yo reset your preferences? There are a number of ways
There's a deeper clean method in the details below
Try resetting your preferences: The easiest way to reset everything is to delete the InDesign preferences: as soon as InDesign starts to boot hold down Shift, Alt, Ctrl (and Apple/Cmd if working on a Macintosh). A dialog will appear asking to delete the InDesign Preferences, select 'Yes' on this dialog.
