Running Mac OS 9.1 with 256 Megs of Vertral Memory when I start mac messenger it is running fine at it's alloted 8 MB of memory. But after opening a couple windows and chatting it will eventually quit with a Address type 1 error, or a code 11 Error (miscalenious Hardware Exception) that takes me way back to system 7. (long time eh :P) If I allow Mac Messenger to have about 28 Megs it will sit constant at about 23.5 MB. I know previous versions didn't take that much. So I don't know if it's a Memory Leak, or if it's with the New Text Engine your using.
