Hmmm, well if you don't see the problem, I guess I will have to play around with it some more...
***********EDIT*************
I just found the problem. I also have a driving wheel on my system and I didn't notice before that DCS assigned the axis commands to my wheel and my joystick when I installed the F-4E. I just removed the wheel assignments and presto, problem fixed! Thanks for your feedback. It made me double check the key assignments!
