I have had no problems with Stuffit up to today. I downloaded a .zip file this morning and it opened it no trouble. However, later today I dowloaded an .sit file: the Stuffit icon popeed up but just stayed bouncing there for about 30 seconds. Then it stopped bouncing but still didn't do anything. It took 2 minutes to open a 86k file!. I have downloaded a few more .sit files today and the same thing happens. Please help!
