When I start up Utilities Premium, the dashboard analysis begins and completes all rows quickly, but won't complete the Windows Junk Files analysis. I even let it run for several hours and it didn't progress beyond 92%. Now it's stuck at 45%. This happened earlier this year (I can't remember if it was the Windows Junk Files or the Internet Junk Files row that time), and after several months it started working again for a couple of months, and now hangs up again. If I switch to the Toolbox, I get the same hangup.
