I'm locking this thread because we have 2 different issues. Besides, the title is so generic that it will attract more different problems. Not to mention it's not a development related issue (you're not writing any code for aMSN), but rather two platform-specific support requests.
@Control: follow the thread here: http://www.amsn-project.net/forums/index.php?topic=8138.0;topicseen
@BrownSugar : I guess you are on Mac too, if you mention it bounces on your dock, so follow my advice to Control.
@itdcmy : Please make a new thread and paste your status log (Ctrl+S) and protocol log (Ctrl+D), censoring out sensitive data such as email or IP addresses.
