Okay, I'm using WLM 14.0.8050.1202, with Messenger Plus 4.80.0.356. This only affects Msg plus on Windows 7, haven't found this problem on my Vista computer. When you have tabbed chats turned on, and a new tab is opened, the window's height shrinks. I don't know why, but I think every time a fullscreen app's resolution changes whilst WLM is running, it shrinks it to the Height of the screen. I couldn't get it to change back to normal by just changing the res. outside of a program. Please fix this, it's rather annoying having to make chat windows bigger every time I change to a different window =/
