Lightburn 1.7.07, windows 11, lightburn pro, gweike g2 fiber 50 watt.
I had been using lightburn to test making marks in black pla 3d printed plastic (500mm/sec, 20% power, 20khz, 300lpi, 1 fill pass, 1 line pass same power makes very good grey marks on black PLA, color matters, black works well, green barely, other colors not at all) and I created a new material library, and a new entry in the library, saved it, realized I had an older material library, loaded the old one, merged the new one, auto-rename, it took me to the save dialog, I told it to save the new 2 entry library under the old name.
Lightburn immediately crashed, no messages. I looked at event log, didn’t see anything.
Is this a known bug? Is anyone else able to reproduce? I lost my then-current canvas/workspace but no great loss.
