I'm running 98 se and have not been able to fix this problem. When I click on control panel, The "explorer" box pops up and says Explorer has performed an illegal operation, contact your software vendor. If I hit "close"
the box closes and then opens the control panel and everything works as it should. Reloading 98se did not fix the problem(I did not reformat, just ran set-up again). I have run scanreg / fix and also sfc. Thank for any help
