I've tried all the the CVS builds of DOSBox, and i'm currently using the AEP CVS build. It runs very good, but i've notices some strange behaviour with the ddraw output. When DOSBox is running in a window, i get a "Failed to create ddraw surface, back to normal surface." message, and the window will not stretch to 800x600 (the value i have set in dosbox.conf). Fullscreen mode works ok, without an error message, and the image is stretched to the values in dosbox.conf. Previously, i was using output=overlay, and didn't get such a warning, but that output mode is much slower than ddraw.

Could that be a bug? I'm on XP SP2, with a Radeon 9600 Pro (Catalyst 8.351-070302a1-045035C-ATI).
