GammaRay / KB Emulator / FPUIPC / Project Magenta - key assignment problems.

I'm attempting to iron out a bug without much success.I'm using a Gamma Ray USB, Keyboard emulator, FS9, and Project Magenta all on one PC while testing a protype EFIS / MCP. At this stage all I have are toggle, pushbutton and rotary switches.I have assigned a bunch of keys to the buttons and swtiches of my EFIS and MCP using Keyboard Studio.Within FPUIPC Keys, I have mapped these keys to Project Magenta functions using a mixture of both 'cataloged' PM functions, and the "PM GC Controls (by param)" option using FPUIPC offsets as the parameter. Just about everything is working beautifully - although I have to ensure the FS9 screen is active for the key assignments to work correctly - which can be difficult when not all MCP functions are yet modelled on my hardware. Here's the problem: For some strange reason, my VOR1-Off-ADF1 and VOR2-Off-ADF2 buttons occasionally reset themselves to VOR1 and VOR2 - and at the moment it's whenever I flick the VNAV switch (previously it was the rotary modes selector that would do it, but I seem to have cured this problem by re-defining the keys).I'm just wondering if this is solvable. The FPUIPC keys interface, together with Keyboard Emulator, FS9 etc. all running on one PC can provide plenty of potential for technology confusion - and on more than one occasion I've had to reboot. Is there a more elegant way to do this on one PC ? What do I need to look our for with all of these key assignments whizzing all over the place ? Finally, can anyone suggest a fix for the VOR-Off-ADF issue outlined above ?Thanks,Paul
