I also have a problem with the contact list disappearing. I'm using Adium X 1.0.4 on Mac OS X 10.4.9, but have been having this problem since version 1.0.
Steps to reproduce:
- In Preferences > Advanced > Contact List, set the contact list to hide on screen edges
- In Preferences > Appearance, make sure the window style for the contact list is NOT "Regular Window" (ie the contact list is completely invisible when no accounts are connected)
- Move the mouse away from the screen edge (so that the contact list is hidden)
- Put the computer to sleep (or just disconnect all accounts)
Wake the computer (or reconnect)
- Before Adium reconnects, move the mouse to the screen edge (which would normally show the contact list if it was connected)
- Once connected, the contact list will not show. As a workaround, choosing Window > Contact List (command-/) two or three times will show it again.
