This might be an X-server problem. What X-server are you using? On my
Linux system (S.U.S.E. 4.0 + XFree 3.3.2) it's running perfectly.

No. The VM allocates all the memory used by the image beforehand and never
shrinks or expands it afterwards.

Does it happen with a fresh image or have you set up your image to run
any special stuff (say, PWS or such)?
