Something odd: When I attempt to uncompress a set of .RAR files, the program will lock up. However, I can't see how to get the program to quit since UnArchiver does not show up on the ForceQuit menu. I'm assuming that it has something to do with installation, but I am still unfacile with the Mac OS so I am not sure as to how to troubleshoot it as I would with a PC. Help/Hints? Oh yeah, version 1.6 on a 10.4.10 MacBook.
