WinXP pro sp3 and Office 2003 pro full install. I have a user, my boss, that when opening an excel file on the shared network drive, will get a blue screen and has to restart. Does not always happen and not always the same file. She opens files by starting excel first and then file, open. I have uninstalled and reinstalled office and ran chkdsk. Others do not have the problem when opening the same file.
