Bought my son a Saitek yoke/throttle quadrant for Father's Day.
Everything works except the mixture control. He runs FS2004 on a
PC with Windows7. Tried hooking up his yoke/throttle assembly to
my computer (PC running windows7 with FSX) and the mixture works
fine.  Are there any software "glitches" or "fixes" inherent in
FS2004 that would prohibit the mixture control from working? I
have checked all of the control settings in FS2004, same
assignments I gave them in FSX.
