I was in a Vatsim controlled flight, when I went to change the NAV radio to the ILS.NONE of the radio knobs worked! I couldn't switch any of the NAV or COMM radio numbers at all. Transponder worked fine.Has anyonme else come across this?Gavinhttp://www.interprom.com/gavhttp://www.precisionmanuals.com/images/forum/ng_driver.jpg

Yes. This seems to occur periodically when running FS in a window. If you select the full screen option all of a sudden all your buttons and knobs start working again. You can then go back to running in a window but sometimes a freeze will then occur. It is hit and miss and probably due to a resource issue rather than a program one.Warm regards,Jerry Wake CYWGWJA125

IS there another way to change the NAV frequencies then?Gavinhttp://www.interprom.com/gavhttp://www.precisionmanuals.com/images/forum/ng_driver.jpg

Tried turning avionics off and on? (shift F12)

Happens occasionally to me when I use a different aircraft.You'll need to load a different aircraft(usually the cesna to me) and turn the avionics button on.Enjoy :)John (Once known as Macs)http://homepage.eircom.net/~eamonnmca/images/logo_ba.JPGwww.bavirtual.co.uk Senior Captain Simflight.com Staff Reviewer

on the overhead panel switching Batt on and then off again helps for me
