1) You can always resize the wmp window, like toddy said, so you have both the wmp-window and a convo window on your screen. And you can click/open/close concowindows as you like of course...
2) You can even set wmp to always be on top...
3) If you got Windows XP, then right click your taskabr and select "toolbars > window media player". Now if that is ticked, you can just minimize WMP and it will show up in your taskbar. Now you can easly open the visualisationwindow by clicking on the righttop icon in that wmp-bar...
4) Why do people always want to integrate/throw everything into 1 program??????? and when everything is put into 1 program, then they complain that it is bloated and uses to much memory *sigh*
5) Like toddy said, how are you gonna watch a movie and chat with different people at the same time? O_o
