I'm using DOSBox 0.72 on a laptop running Ubuntu Hardy. It has an integrated graphics adapter by Intel (GMA X3100). I have a dualhead setup with an external flat display. DOSBox doesn't want to co-operate with it, however.

After switching to full screen mode I get the same image on both displays and when returning from there I also have the same image on both displays in X Windowing System. Is this intended behaviour or a bug? If it's not possible to have DOSBox on just one display, it would at least be nice if it returned successfully from full screen mode.
