Today I had all the model and support parts turn crazy colors whenever I put the mouse over them and they all became unselectable.  This was right after auto-adding supports.  I wanted to delete a few spurious supports but couldn't.  I just let it run and the model seems to be printing, although the little image on the printer screen is also weird colors.  This was the most complex model I've done in Chitubox so it might be a memory problem, although I have 16GB of ram.  Everything stayed working and only did this when the mouse was over the parts.  But the annoying thing is that I could not select the supports.
