I should also mention that fleets in higher orbits do not get maintenance from maintenance facilities on the planet. I could come up with some type of maintenance distance limit, perhaps based on a tech line, so that fleets in higher orbit can be maintained. If I do this though, I probably should have show some sort of slow-moving maintenance traffic that can be attacked.
On a side note, it took me about six hours to get VB to draw partial orbital paths so that fleets and contacts can be shown with curved tails when in orbit. It became considerably easier once I remembered that the VB circle function counted degrees backwards and started at what we would regard as +90. Until then, there was a certain amount of frustration at VB's apparent illogical arc drawing
