Just to add to your woes and to add a bit of diversity. I would like to point out that this does not only apply to Ubuntu as VM on a Windows host.
I have exactly the same problem with Lucid, running under VM Fusion on Mac OSX. Interestingly, i only built this machine today and only had this problem once i updated the machine. I built the initial VM using a beta1 ISO and everything was wonderful.
Unfortunately i have not been one of the lucky ones and been able to use the onscreen keyboard to login. I have no way to log in whatsoever, the keyboard does not come up if i try using the onscreen keyboard. No matter what i do the minute i tick the box, it disappears.
