I am working on three different multi-layered images in Affinity Photo 1.9.3 and using the Freehand Selection Tool without any issues until, suddenly and only with one of the three images, the FST will only make selections like it is in Polygonal mode. Regardless of what I do with the settings, it will not make any selections in Freehand mode.
This does not happen with the other images I am working on, just this one particular image. I have tried closing/re-opening the file, copy/pasting all the layers into a new document, restarting AP and rebooting the Mac – all without any success. The FST still does not work in freehand mode in that one particular file only.
Am I missing something really obvious?
