I recently upgraded to IE8 and upgraded to the current version of CCleaner. Now, every time I run CCleaner, it sticks on IE's index.dat file at 5% progress. I even unchecked the box for scanning index.dat files and still have the same problem. I reverted back to an older version of CCleaner and still had the same problem. Has anyone else experienced this problem and does anyone have any suggestions for correcting it? (short of uninstalling IE8)
