Every time I use the mouse to click on a cell in Excel 2000, click again to make the flashing typing cursor appear to make changes to a cell, click on another cell it performs an illegal operation: ---- EXCEL.EXE caused fault #c0000005 in EXCEL.exe at address 0177:3006d7bf Registers: EAX=0062e043 CS=0177 EIP=3006d7bf EFLGS=00010246 EBX=00000000 SS=017f ESP=0062d81c EBP=0062f904 ECX=0064ce89 DS=017f ESI=00000000 FS=24df EDX=00687740 ES=017f EDI=00000000 GS=0000 Bytes at CS:EIP: 66 89 31 83 c1 02 0f bf 42 fa 85 f6 0f 85 bb c7 Stack dump: 00000001 3006cc83 0000f723 0062e043 00687738 00000002 00000000 0068d484 00000118 81d725cd 00000040 81d7139c bff39546 81d7139c 81d725d1 835e3ff7 ----- It gets very fustrating, especially if I haven't saved the changes! I had to install Norton Crash Gaurd to let me save even if it crashes. But I am beginning to get sick of these Norton popups! Yes I have reinstalled Office 2000, in fact I reinstalled Win98 and Excel 2000 still crashes when I double click a cell then click on another cell. Any suggestions to help me would be very appreciated!!

When you said you reinstalled 98, Did you FDISK then FORMAT your hard drive ? Simply reinstalling 98 over your existing 98 operating system WON'T do it for you. And when you reinstalled Office 2000, Did you remove it through Control Panel > Add/Remove programs or did you manually delete it through Windows explorer. If you just deleted the file itself through explorer, That WILL NOT FIX your problem. When removing applications, ALWAYS USE ADD/REMOVE PROGRAMS in Control Panel, or use the uninstall option. Good Luck !

To answer your questions, yes, I have used FDISK then Format the hard drive and yes, I have used the add/remove programs. This still doesn't solve the problem!

This same problem is happening to me. But mine says: EXCEL caused an invalid page fault in module EXCEL.exe at 016f:3006d7bf.
