I have a user that can open Excel, open SOME files, but encounters page faults when he tries to open others, or if he tries change the size of the cells in a new workbook. I have reinstalled Windows98 from the CAB files, uninstalled Excel 97, deleted the directory and reinstalled Excel 97, but I encounter the same error message: EXCEL caused an invalid page fault in module GDI32.DLL at 015f:bff21cbe. A register and stack dump follow. Any suggestions?
