This may be a one-off and not a bug, but I just experienced many Access violation errors when I closed down RadioBoss.
The SW had been running for quite a while so maybe it had been building up over some days. the exacat error was:
"Access Violation at address 007155F1 in module 'radioboss.exe'. Read of address 00000008"
It wrote "information messages" (pop ups) multiple times, presumably one per message. I thas started up ok after, and closed down ok as well.
