Hello, just purchased the NG 600-700 and I cannot tune the nav or adf radio, from the radio panel.(737-600vc-700vc wingtip model)The plus and minus icons show up when the hand cursor is over the buttons but when I press down on the mouse button the frequency does not change in the frequency display boxes nor do the switch buttons work for switching the standby frequencys to the active frequencys.I did not do any initalizing of the FMC due to the fact I just want to fly with the navigation radio's first before I tackel the FMC.I tried changing the frequency while the sim was running in full screen and windowed mode and when the radio screen was in docked and undocked mode but no joy.Second problem with a winter season at night when I select the overhead pannel and choose the panel bright switch the graphics on the overhead turn a brownish color and the display becomes unreadable.I am using the latest NVIDIA drivers and the card is a 5200FX 128 meg.Windows xp 512 meg mem, onbord sound analog devices soundmax.Thanks for any help with this,Mike "Hawki" Levine

Solved the overhead pannel nightime problem my system was set for 1024x768x32 colors but the sim was set for 16 bit color, therefore bad coloring on the pannel.However the nav and adf radio frequency selection does not work at all.Thanks for any help on this.
