I'm getting the repeat bug again. It is definitely caused by my use of Alt+F4. No other button press with any combo of Control or Shift +key causes it. If I change the keyboard repeat rate, the Flirc repeat rate follows. It is not a remote problem as I use a URC Aero and it shows when it is sending signals. Another tell is I can cover the Flirc while it's doing this and it continues to send repeated signals. The only way I can stop it while it's in this loop is to press another key. Funny thing is the Flirc was behaving perfectly until I had an idea and decided to try troubleshooting the disconnect bug. Ah well....
The noise canceler didn't help at all.
Will keep trying to isolate it.
