wine users - Feb 2003 - fullscreen

hi,
i have some old programs that run only at 640x480. they work fine under 
wine, but are a pain to look at when my resolution is 1600x1200.
can wine scale the 640x480 window to full-screen (that is, either scale 
it to 1600x1200 or change my X resolution automatically, and change it 
back upon exit)?
(something like alt-enter in the windows world)
i couldnt find any mention of full-screen in any of the documentation.

i can of course ctrl-alt-+ but this is pretty ugly.
