Thanks for the update Markus. I updated the eCOS and WDP, and everything seems fine.. The only challenge is that the WINZIP installer is in German text - fortunately I managed to guess the correct button to start the installation.
UPDATE: Thanks also for fixing the old problem of WDP reset when the eCOS "GO" button is pressed after a derailment.. It now works a treat...
Every update brings us closer to perfection..
