(SU Enscape-Setup-2.3.2.703-g2edb284)
When using the Screenshot(to file) button to export an image, if there is an existing image you are trying to over-write SU crashes.
{edit}... I may have jumped to conclusions...
{edit}... computer re-boot has fixed it; sorry - please delete this thread.
{edit}... or not: I managed to overwrite 1 image, then on trying to overwrite the next one it crashed again. If I delete the image first, then it seems to be OK as long as I don't delete it from the 'save -as' explorer dialogue.
{edit}... It seems that it's only this one model... I'll raise a ticket.
