I use Chromium on a Raspberry pi5 (8GB ram) running stock Bookworm.
Website course designer has worked very well for years.
Now with the new version I get regular crashes while adding points. The screen goes white and I can't do anything with the map, but the menu still works. So I have to start again. It does it randomly.
There used to be a very useful reverse course facility that was able to reroute around roundabouts. Now when I reverse the start & end points it makes no attempt to reroute the roundabouts and when I attempt to move points or add & move points on the roundabouts, road rerouting automatically takes over and draws lines everywhere seemingly trying to - well, who knows what.
When selecting my British postcode as a start point, it no longer properly centers on my house. So after zooming in, I then have to drag the screen around to find my house.
I know we can't go back to the old website but please stop changing things for change's sake and in the process break what was a very good tool.
