Hi, thanks for taking the time to reply.
I've now changed the "Additional buffer-level checking" value to 0 (was 4).
Still it didn't fetch any RC5-72 packets after an update...
No big deal though, as I'll be concentrating on OGR, but it'd be nice to do a RC5 packet once in a blue moon to retain my position, so any further suggestions are welcome

Using 507b btw.
