I've noticed that using the scroll wheel in the research window ("naval", "generic" and "available" screens) leads to a crash of the game when there are not enough technologies in that screen to make scrolling available.

with the events: I got the "ammo" event, and I launched it. But the card remained with the others at the bottom left of the screen. I clicked again on it, it couldn't be launched again, so I clicked on the "abort" button. The card disapeared, and I never got the extra ammo ...
