--- Comment #6 from Vincent Povirk madewokherd@gmail.com 2010-08-23 17:33:44 --- Apps should still be able to set the resolution of a virtual desktop to a smaller size. This works without changing the configured value, and still leaves winecfg usable.
If an app really needs to be started with the display set to 320x200, I think it's reasonable to have to set that using explorer or regedit.
