Steel Panthers bug ?

[Iwo Jim]

I have this happen all the time since using new laptop with Vista Alt&Ecs minimizes the game to task bar then just click on it again to return it to full screen and should return colors to normal this usally works for me, on other problem I've noticed playing any version of spwaw is using the artillery screen game acts very sluggish trying to plot a shoot is very as you have to keep left clicking to try and select a hex....has anyone else had this problem
