#4 updated xcsoar-registry.prf in /data folder not used

[nbonniere]

further analysis:
I installed condor2nav on other PC and it worked OK, but when changed xcsoar-registry.prf in the /data folder, it didn't use this new file. In fact when I changed the name from xcsoar-registry.prf to xcsoar-registry.prfx, condor2nav didn't report not finding the file as it does the first time if the file is not there. Original file is cached? How do you reset/force using the new file?
