OK, I'm back and testing :-)
I've tried to repeat the altitude filter map freeze problem, and everything is working just as advertised now. The only thing that I did different this evening was to put EGLL into the SmartView > Select Airports box and hit Enter. This box was empty but the Auto Set QNH was ticked. Is there any chance that this was the problem?
A bit of background on how I ended up here:
- Renamed my RadarBox directory to avoid overwriting with the new install.
- Did a completely new install using the full download posted.
- Ran this new install briefly to make sure all was OK
- Exited RB and renamed the new install directory to New
- Renamed my previous RB directory to the correct name.
- Copied the anrb.exe from the new installation to my original directory to give me all my custom outlines, D008.dat file etc
- Ran RB (new exe in old directory) and this is what gave me the empty Select Airports box.
Maybe nothing to do with my map freeze problem, but that's the whole story :0)
RB running without any problems now with the Altitude filter set to 0-15000. Testing continues, but everything looks good!
