Hi, When I start the application - Set up Services - tick on Foursquare and click on Authorize... I get the message Authorizing ZapLoc with Foursquare and the progress bar shows moving ones and zeroes. But nothing happens - it doesn't open any browser window to authenticate, just hangs there until I click Abort. Tried uninstall / reinstall, uninstalling removing all dependencies by apt-get autoremove --purge zaploc and reinstalling, but no change.
