Glock, the comment might have been a little off, but he *does* have a point. After all, a joystick is listed in the System Requirements for AH2. If you decided you like AH and want to keep playing it for a while, i highly recommend you get yourself a Joystick myself. Doesnt have to be anything fancy. 4 buttons and a hatswitch, maybe even twisty rudder, is quite enough for starters. It makes a whole bunch of things a lot more easy and youll certainly find that your 'skill level' will jump a few steps up.
As for the right click not working..... I dont really have a good idea what might cause this. Do you press any keys/buttons before this happens? Maybe your hitting U and find yourself in bomber calibration mode without knowing it (the cal mode 'works' in fighters, too). Try to find out if theres something you *do* right before it stops working. Or is it after a certain time?
