All Menu Items Greyed Out CS5

[joshrives]

Everytime I use Photoshop CS5, at some point all of the menu items get greyed out and don't come back unless I quit and reopen Photoshop.  There doesn't seem to be anything that triggers it.

All the keyboard shortcut and the mouse and tools work fine, but I can't select any of the menu items in the dropdowns in the menu bar (Photoshop, File, Edit, Image, etc)

This is obviously very annoying...any ideas?

Arty, have you tried updating via the help menu?:

Keeping Photoshop Up-To-Date: http://adobe.ly/PS-Up-To-Date

Or are you trying to download the update from Adobe.com?
