Very rare, but, I have had a couple of concurrences where radar contact stops responding well into an IFR flight. As I said this is very rare to see, 99.9% of the time RC works correctly. Any ideas why I see this every once in a while? Windows 7, 64 bit PC, I7 930 processor.jim

If you alt-tab are there any hidden error messages displayed? Does any action such as you or RC tuning the comms precipitate this hang-up? What version of FS are you running.What add-ons are simultaneously running. If you are using a networked system what's on the FS host and what's on the client.If you have the comms and miss an "ack" that can hang up RC waithing for your acknowledgement.

without a log, there is no way i can tell what happened.if it happens on one particular flight more than others, run debug when you are flying that route. make sure you click debug BEFORE loading the planjd
