--- Comment #4 from markk@clara.co.uk 2010-07-22 11:38:15 --- Another program with a very similar problem is Melker - The Elk Hunt by Wihlborg Entertainment, which was marketed as Moose on the Loose by eGames/Greenstreet games. A demo can be downloaded from http://www.wihlborg.se/melker_the_elk_hunt.html
After installing, run melker.exe. Instead of a picture of Melker the elk near the top of the window, that area is blank (grey). In virtual desktop mode the picture does appear for a moment, before it is overwritten.
Similar to the Disney programs, when not in virtual desktop mode moving the window causes the picture to appear. When in virtual desktop mode, if you drag the window so any part is off the screen and back, the picture appears. (I guess because the window is sent a message to repaint/redraw itself?)
