>PS maps do not work on initials run, as all the th2 file has is empty scale. Shame it causes a fatal error, it would be nice if it was just a warning that nothing could be produced, but in my default file I just have the map export commented out

Do you mean empty scraps?

Hmm, pretty sure empty scraps are OK (there was a bug where ‘debug on’ caused a crash and it was fixed in 5.3.11?)

Still, a memory is a dangerous thing after a long caving trip – I’ll report back – but not soon.
