[Q]

Tried a larger combat in the simulator of the demo:
two empires with each about 20 dreadnoughts and a carrier with about 140 large fighter.
The fighters were launched and proceeded the ships.
When the two fughter groups opened fire the game froze.
I waited for more than 15 minutes but nothing happend.
I had to restart the computer, not even the task manager could be activated!
Athlon 64 3400+, 512MB RAM, Nividia GeForce FX 5500, Windows XP Home.
I have to add that until this I had absolutely no technical problems with the demo. Therefore I think it is just the number of units that killed the combat, but 280 fighters seems not that much to me.
