Thanks. I wondered if that was a possible reason, so I connected the PC to the net, but it didn't seem to fix it.
Will have a fiddle with the app data files.

Just wondering if anyone else has seen this happen.

The routes load as a total mess, but it seems to happen if the initial TSRE page doesn't display the screen shot of the image looking down the line under the overhead.

This was version 67953.

TIA.
