Hmmm
maybe there is an incompatibility with StuffPlug then, please try without StuffPlug and tell me if you are using 32bit or 64bit Windows
yeah the full screen issue annoys me as well... i'll try to resolve it.
Window Manager is discontinued, for WLM try the new, Enhancer for contact list docking, auto-hide, hide taskbar button, remove button flashing and remember keyboard layout in conversation windows
Messenger Plus! Live Enhancer
