Hi i'm experiencing this random crash with excel. 2 users had the same excel file open in the background (so they weren't working on it) when experiencing the problem and then with no warning & when doing nothing specific all of a sudden excel gave an error that it needed to be closed. It then re-opens asking which files to recover etc...
Error signature:

Faulting application excel.exe, version 12.0.6331.5000, stamp 48fa2869, faulting module oart.dll, version 12.0.6214.1000, stamp 47069fb7, debug? 0, fault address 0x0004abbb.

This is excel 2007 on a windows xp system.

I've noticed this problem with 2 different users on 2 different pc's. But i'm pretty sure it's not the excel file because i had a 3th user on a 3th pc have the same excel file open on the background the whole day & nothing happend at all... Any help would be greatly appreciated!
