For a long time now I have been trying to add the FMC gauges from several commercial products I have to either freeware or default planes and so far I haven't been able to get any of them to function once I've added them to the target plane panel.cfg.  I have Wilco's 767PIC, Airport 2000 vol.3 and PSS 747/777 and I have tried adding the FMC's in each of those to other planes.  The best I've been able to do is get the FMC bitmap to open but as soon as I attempt to use it either nothing happens or I get error message on the FMC display stating that data base is not available.  Does anyone at all know anything about how these guages are configured?  I have succesfully added other gauges to panels including two different INS panels but so far I've had no luck cracking the secret to commercial FMC gauges.  Any help would be appreciated.
