Sorry to resubmit again. I didn’t realize I ran out of space and 1/2 the info. I put on was cut off. To keep it simple, I won’t include all the stack dump info. Problem: When trying to delete ANY folder within windows, explorer performs an illegal operation. I can delete anything else apart from folders. Even if the folder is empty, I can’t delete it. My system is not affected as such but it is bugging me and because explorer has caused similar problems in the past I want to call upon all of the knowledge available at this site to try and solve it. I am running a Compaq Presario Notebook 1600 XL with Windows 98. I have tried: restoring registry, reinstalling 98 from the disc and all the other obvious things such as extracting new copies ofkernel32 and explorer.exe. I will keep question open 2 days and whoever can solve gets all my points. Appreciate the help!
