Hi, I have an old computer runnig windows 98. To secure it from malware I installed spybot and teatimer. Everything works just fine except when the system is idle for a while a white error message pops up with no text and only the button close. If I click close teatimer shuts down and the whole system becomes unstable, I get "not enough memmory" messages when trying to run applications although I've got plenty of memory. Is there any way to fix this? I would rather not disable teatimer since Windows 98 is so insecure.

PS: I checked that it is not a conflict with the screensaver. This problem occurs even with the screensaver disabled.
