Hi Dean,
Maybe quick preference reset may do the trick?

Tip One: Quickly reset Adobe software preferences.
There are times when you want to reset programs to their default settings. We’ll often do this when troubleshooting odd problems. It can also be handy if you share a machine or just want to get back the factory settings for workspace, shortcuts and general defaults.
For almost any Adobe product, don’t waste time digging around for preference files. Just hold down the following keys immediately after you launch the program:
Mac: Command+Option+Shift+Control
Windows: Control+Alt+Shift
A dialog box will give you the option to delete or reset the program’s preferences (the wording varies between apps).
This tip works for Photoshop, Illustrator, InDesign and even Adobe Bridge!
