I briefly got it working with the "Terry" profile and direct assignments, but it's glitchy. It's almost as if the hat is being pressed repeatedly or incompletely or something. I noticed the same problem with TMS keys assigned in the
Saitek profiler, resulting in my having to use Advanced assignment to do 0sec keypresses. But that wouldn't allow TMS to be held (for TWS on and HMCS FCR slaving), so I set the pov hat in the profiler to unassigned and just mapped it in BMS directly. But DMS does not appear to be functioning even that way. And H2 hat does show up and works fine in everything else as far as I can tell.
Correction, DMS down is working for the HMCS show/hide. So it's just not doing anything with the MFDs now with DMS assigned directly. Do you have to assign the flip pages, or something?
