Task manager shows that CCleaner is not running.
Just noticed something...after a reboot and if I open a browser and subsequently close it CCleaner will work as expected. If I re-open a browser and then close it the CCleaner icon flashes a couple times but does not clean. Then, as before if I run the cursor over the icon in the taskbar it disappears and is not in the overflow area and it does not clean the browser. Bottom line, it works one time as expected after a reboot.
Just did more research and found that if either a Task Manager window is open or if CCleaner window is open CCleaner will work as expected consistently. Tried opening and closing a browser a half dozen times with the Task Manager window open and CCleaner does fine. Once the Task manager window is closed CCleaner will close and not perform a clean. This is also true if I leave a CCleaner window open on the desktop.
Any ideas?
