CH Throttles dead spot PMDG 737 NGX

[wsuch]

Hello

I have an annoying issue with the CH throttle quadrant configured through the latest version of FSUIPC for FSX, when I configure the reverse thrust detents on the CH Throttle quadrant there is a large dead spot when moving the throttles before I get an N1 increase seen on the throttle quadrant in the 737 NGX also. In FSUIPC on the throttle calibration page if I select no reverse thrust zone the dead spot is gone and n1 increases immediately when I move the throttles, the reverse zone seems to work for all other aircraft except the NGX IE i dont see the dead zone with other aircraft configured this way, worked fine in FS9 with the old 737 PMDG. I have logged this with PMDG in the hope that someone there might known what is causing this but on the off chance there is a know fix I post here, thanks very much
