Recently (past week only), I have had problems when choosing APPLE+ALT+P to bring up the Document Setup dialog box. I seem to constantly have to repaginate using the page tool, because the margins shift. Once I go into the Document Setup, I click on Page Setup and Illustrator immediately crashes giving me an "Error type 2" message.

Is there anyone else experiencing the same thing? It seems to be isolated to this issue only. Any thoughts would be greatly appreciated.

I am using a grey G4-500MHz tower running OS 9.2.2 and have 768MB of RAM.
