InDesign, CS5, version 7.0.4 problems
Font menu is blank with the exception of a few arrows.
Can't change 'regular' to bold or italic. No options are shown when I click on the arrows.
Can only have one 'type & table' box open at one time.
When I select the selection tool the text I was previously working on disappears.
Can't place photos from 'Photos' into inDesign.
You can try trashing your preferences, but it sounds like you’re on El Capitan. If so, CS5 is unsupported and will never be updated.
Roll back to an earlier operating system.
