I did rebuilds all the way back to "git checkout wine-0.9.50". The problem reproduces all the way back to those versions. This means that ANY of those builds of wine shows this problem under Ubuntu Hardy (kernel version 2.6.24-16-generic). This wine application did not show this bug under Gutsy (kernel version linux-2.6.22.14).
I guess some function now returns a value that it didn't before. I'm not sure what to do now, as the problem now seems to lie somewhere in the middle between wine and Ubuntu linux core development.
Note: The behavior at start-up changed to the behavior of those earlier versions: the iconified version did not show up at the desktop.
Have you filed a bug with ubuntu? You might try switching kernels under gutsy or hardy to see if that's where the problem is...
