[Elecraft] K3 not completing all events when changing frequency by direct keyboard entry

[DeYoung James]

I do a good amount of direct frequency entry from the keypad.  About 50% of the time when I hit the FREQ ENT button, punch in the frequency, and finally hit the AFX/[return] button some actions take place but not all.  Most obviously, sometimes the relays don't reset to the new settings, the signal bar graph gets either stuck w/no signal or is pegged, no audio heard, etc.  It seems to be random when it happens and how it "hangs".  I try to make sure that I hit the AFX/[return] button centrally and with enough contact time to be sure it takes.  However, I'm still getting the "hangs".  Any ideas how to fix this?
