In a network enviroment, I have an user with Winows95,Office97, and everytime she tries to access an Excel spreadsheet that is shared on the network, she gets This program ha sperformed an illegal operation and will be shut down, under details it says, an invalid page fault in module MSO97.DLL at 0137:####:######. No one else is having this problem. I have gone as far as removing Office97 and deleting the registry keys, then restarting and reinstalling Office97. When I try to open the shared spreadsheet I continue to get the message. Any thoughts would be greatly appreciated as I have spent 2 days trying to figure it out. Thanks
