Short description of error
Intermittently, attempting to save a render will lock up computer, sometimes produces blue screen.
This doesn't happen constantly, but out of 12 renders, 4 caused my computer to lock up when trying to save them. Re-rendering and saving seems fine as the issue is not produced on every save.
Exact steps for others to reproduce the error
Save a rendered image.
