Could you add the local Printer Queue to the list of things being cleaned? It would be a helpful addition and if everything is working then it would already be empty so there shouldn't be any real dangers. I can understand not messing with network printers, but if they are connected locally then this would be helpful. Love the updates and progress of this utility, it's vital in my PC tool belt!
How about putting the last Beta (which i had no problems with) back out for download until you get the fix sorted out. Like you do for the Windows version under FileHippo. This will allow users to clean their macs without bugging you constantly. I've used your software for years on PCs, so i was happy to see you develop a Mac version. I've no doubt you'll get it right, just wish i could clean while i am waiting.
