If i understand your explication correctly, that should only apply if i
were actively polling the mouse, right? At the moment i'm not polling
any events other then MOUSEBUTTONDOWN & MOUSEBUTTONUP, and the same code
in window mode seems to have no problems.

At the moment it's not that important tho, i'll look into this later-on.

Thx for the help tho ;)
