I really dislike the new way ccleaner works. I used to be able to click ONCE and be done, now I have to click twice in two different places and ignore the attempt to sell me a product on the last page.
Also, I have never understood why the window has to be so large. On my wife's laptop it extended beyond teh screen with no way to resize. There's NO REASON why it has to be so big. It is very inconvenient.
