As of last night, my Adium has immediately quit when I send an Instant Message. I haven't made any changes to the system or any changes in Adium Preferences since I configured them to my liking when I first got my computer (3 weeks ago). iChat works fine. I reinstalled the program but without success. I realize that Adium hasn't reached a 1.0 release yet so this may be one of the bugs that needs to be worked out, but I have friends who use it and have not had this issue on their MBPs, MBs, or PowerBooks. Here's the specs on my system: MacBook Pro 2GHz Intel Core Duo. 2GB DDR2 SDRAM. Mac OSX 10.4.7. Any suggestions are appreciated.
