To clarify and after a bit more testing ..
I am using track ir and previously, using the hotkeys assignable by their utility I could center, pause, or switch track speed mode.I could then program the saitek controls to the hotkeys (IE ctrl f6 for example) and everything worked within Ah2 as the commands were passed on to the system.
When testing outside of AH2 it works as previously using their test screen, with the saitek controls but now it seems that we no can do the passthrough of keystokes whether it be a la saitek or manually.
The last time I used such functions was about 8 months ago using Vista32 .Since then I have only used the trackcenter command within map joystick buttons within ah2., but I have also gone to Vista 64.
I suppose in hindsight that this could be another vista security issue but I am not sure..
