No, the file is not read only because when I found and log a cache I got it in the file. But if I delete the file the next time I try to log a cache, the file is not created. that's the problem
My GPS do not create the file "geocache_visiits.txt" when I found (or didn't find) a cache. But if the empty file "geocache_visiits.txt" is present, it,s OK.? What can I do ??
