Hi:
I upgraded to IE8 ver 8.0.6001.18372 a short time before last CCleaner version 2.16.830 was installed. I do not know if this has anything to do with problem as outlined below, but it started shortly thereafter.
Now when I run CCleaner most of the time it will clean all but (1) Internet Explorer History file 5.0MB in size. When I run CCleaner immediatley again sometimes it will still show the (1) 5.0MB again. While other times it will show "0" like it always did after second repeated Run Cleaner. Sometimes I have to Run CCleaner multiple times to get it to "0".
In addition, the blue border at the top of the CCleaner screen blinks from the normal dark blue to a lighter blue in color upon opening CCleaner.
