I have the same prob, but not only in the options menu. It is also ingame and it is very anoying when trying to select an enemy. I know, you can press "r" but it's not always the one you want to attack. Also selecting battleships or even planets are difficult to select. I drastically decreased my detail and resolution, but now i don't like the game that much anymore
Please help, these are my comp. specs:
amd athlon 2000+
geforce 2 mx 64 MB
768 DDR ram (i even bought more for this game! i first had 256)
Microsoft intelli mouse explorer
and yes, i tried several video drivers and downloaded the newest mouse drivers (wich actually made my performance worse)
