InDesign CS4 Middle East version

[RonLF06]

I'm near finishing my 4th English/Arabic book design, and suddenly InDesign is refusing to show grids, text and picture box frames, and guides.
Keyboard shortcuts don't work (Command and nor does the Menu (View>Grids & Guides>Show guides).
I've restarted the computer (G5 desktop, OS 10.5.8) and uninstalled and reinstalled from disk. No change. Is there something I've missed in Preferences?
Can anyone help? The publishing deadline approaches fast!

Uninstalling and reinstalling does not reset user preferences.

Try creating a new user account on your computer and then open the document in it. If it behaves, then you will know that the preferences in your original account were corrupted and need to be reset.
