Shift key for fast jogging not working.

[Ajax]

I'm near the finish line. himits work, M92 p# works, motors almost perfect (need help with "Z"-plot screen is different)(axis move smooth).
Can't fast jog to save my life! (Ajax config- fast jog = 100, slow jog = 10,-Motor speed in "Motor Tuning"=120)
The shift key lights up in the onscreen jog pendant, but axis won't move with the shift key pressed and an arrow/page key.
Slow jogs fine.
Seems like Ajax is not recognizing the shift key.
I don't know how to check/edit the modbus outputs.
I think it may have to do with Modbus 377 not changing.
Also, I'd like to get the "Referencew All" to work.
Can log into this forum, but will not accept my username and password when trying to download the lates software.
Any help would be appreciated. Thanks in advance.

Anyone. . . anyone. . .
