Some users reported waiting a long time for the script to launch: this was because of the Auto-Update check and Run count php script. Relink Bitmaps, when ran, checked to see if there was an updated version from this site and also incremented a counter (run_count_2_08.php) to keep track of runs.
All WebRequests sent to this site have been removed except Auto-Update which has been moved to a button.
