[Pharo-project] Image locked with Display fullscreenOn.

Hello, Got my image unusable after doing a Display fullscreenOn on Win XPSP3 with a 1.3 image. Never had the issue on the Mac. Weird. Any idea on how to solve this without shuttling my image on OSX, changing, saving, and bringing it back on Windows? I made a do.st file with Display fullscreenOff and tried a CogVM.exe xxx.image do.st but to no avail. Help! Philippe
