A sort of fix for the lack of alt-tab is to go to C:\Documents and Settings\INSERT YOUR USER NAME HERE\My Documents\id Software\Enemy Territory - QUAKE Wars\base and modify the etqwconfig.cfg file and change the seta com_useFastVidRestart "0" to seta com_useFastVidRestart "1" this will allow you to hit alt enter to window ET:QW your mouse is still trapped in the window but you can navigate by keyboard. I am still trying to find something to release the mouse, but its a start.
