I posted this on LinuxHam (yahoo group) today. Probably should have posted it here first. Sorry.
The problem does not seem quite the same as Derak's (SP2MKI).
Nothing is appearing on my CQRLOG bandmap anymore. Everything else is working fine. The DXCluster spots come in with no problems and all TRX Control functions are controlling my Kenwood TS-480-SAT without error. Frequency readout is correct. Band and mode switching are working fine.
I am running CQRLOG 1.4.1 with Ubuntu 12.04. I've been using CQRLOG for more than a year and I have never had this problem before. I just upgraded to 12.04 and 1.4.1 at about the same time (not wise, I agree). So I am not sure where the problem lies.
I have tried toggling the boxes "Show only active band" and "Show only active mode." But this makes no difference.
Can you please help me, Petr?
