I think Fyron's barking up the right tree, you need to find a way to let Space Empires render the window at 768 pixels height or more, and have your PC cope with it somehow.

Can you adjust the HUDSettings.txt file to run in windowed mode of 1024x768, and then just allow the very bottom of the SE5 window to run off the bottom of the screen?

That's the best option I can think of. Failing that, perhaps a virtual desktop manager utility would let you run a Windows resolution of 1024x768 with vertical scrolling, if the display options alone won't play ball.
