I just had to reinstall Windows XP Home and all the updates on a new hard drive. I am running antivirus and spyware software. I am having an intermittant problem (every few minutes) when I try to close or minimize Internet Explorer windows or other open application windows. The mouse and keyboard freeze up. When I hit Ctrl-Alt-Del and click twice to close the Task Manager window everything frees up and I am then able to close the other offending window but it is annoying to constantly having to do this. I had this problem about a year ago and if I recall correctly, I found a download on one of the Internet computer forum sites that solved the problem. My chances of finding that again are probably slim to none. Has anyone experienced this particular problem and have a solution.
