Desktop Dead.

[Nocontact]

For some reason every so often my desktop icons stop responding. (Win 98SE). I try to click on the icons but nothing happens. Everything else seems ok but this is of course very irritating.
I know that rebooting will fix it and sometimes over time if I don't reboot it'll fix itself but I wish I knew why this was happening and didn't have to depend on rebooting to fix all my problems.
By the way virus and spyware scans are clean.
Help? Any ideas?

How much memory do you have? sounds like your sys is running slow. How much System Resources do you have free. You may need to free up some system resources

256 MB of DDR. I figured that would be enough, and at the time I wasn't running anything to intensive. Doesn't make sense to me.
