I have a problem with galciv2. Everytime i single click in galciv 2 it double clicks.

For example: If you click the custom scenario button it opens for a second and them closes. You single click next in galaxy setup and you skip race select and onto race customizer and you click next on that and game start(two click sounds). I single click on AI planet and it says I need high intelligence to get access to that when all i want to know is how many ships in orbit(i have to try that five times sometimes). In the research screen i single click on a tech to see what bonuses it gives me or what its for and it automatically selects that(I have to re-do it quite a few times too). And much much more...

P.S. this happens nowhere but gc2(never did, not once)
Please help
