Using Ccleaner version 5.64.7577 (last version for Windows XP & Vista) on a Windows XP SP3 system and occasionally when opening Ccleaner (set to Custom Clean) the Run Cleaner box is grayed out and I must close Ccleaner and restart it and then it works. Never had this problem with previous versions. Is there a fix? Thanks.
By the way, the screen shot below was automatically added and has nothing to do with my question, but it won't let me delete it.
