Uhm... what about just making your browser window smaller... I work at 1280 x 1024 and nver have any windows fullscreen...
That's the whole point of "windows", you can switch between them, and not only by clicking on the taskbar...
If you look at
My little Jedi Knight page (shameless plug) you will see it resizes with every resolution you are in, or any window size you prefer...
But I heard that JedinknightII.net is still working on their design and stuff... So hang in there...
