System Info: Win XP home sp1 w/all critical updates and patches Problem: I have noticed recently, the last 2 weeks or so, my system will suddenly stop responding. For example, just prior to coming here to post this I was finished reading the GRC newsgroups and clicked on the inbox button to go back there re-check my e-mail before closing OE. The system started accessing the hard drive, as usual, and then just hung. I hit Ctrl+Alt+Del to bring up the Task Manager and check the Processes tab, there was PE gobbling up 98-99% of the CPU time. My observations: Bringing up PE and closing it does not end the process in the Task Manager. The only way to end the process was to highlight it in Task Manager and use the End Process button. I can restart PE and all will be fine for a while, the time varies, and then I must repeat the process. Question: Can anyone shine some light on this behavior and offer a possible cure for preventing this in the future?
