i have installed the new version of msg plus live, but now i've got two problems.
first one:
the tabs are highlighted although my contacts haven't written anything to me. i don't know how to describe this "problem", so i've uploaded a screenshot. i think it's clearer then what i mean.

second problem: the chat window gets maximized when i minimize/close all the other windows. but i don't know whether it has to do with new version of plus live...
otherwise the new version is perfect, thanks again to patchou
