SE:V -- Problems after Alt-Tab

[BudgetMessiah]

I've been having some problems with Space Empires V after I alt-tab the game to do something else. When I come back to the game, it doesn't appear to be truly in the foreground. I don't really know any other way to describe it. I can see certain desktop elements showing through (such as the upstream/downstream bars from my Zone Alarm taskbar icon), and when I click on the lower part of the screen, I end up getting dropped back to the desktop, because Windows thinks I am clicking on a desktop item.

I am running Windows XP. Does anyone have any experience with this? The game is playable if I save the game, quit, reload and don't ever alt-tab out, but obviously this isn't an optimal situation.
