Latest version hangs at temp cleaning scan

The latest version almost hangs, takes a very long time, to scan Temp files. After that it is OK. The earlier versions were all faster. Is this a Bug?

Hi yes, and hello. I just wanted to add that I am a new arrival, and ran this version for the first time ever and eliminated over 400 MB of stuff, but when it reached the 98% stage, it hung and after 40 minutes--or maybe 30--I just kind of had to go to bed. It doesn't matter, I was amazed if it got rid of all this unkown stuff.
