I'm working on a painting and several times now the program stops responding to input. I can still click the tools, change layers, select paint color, etc, and the cursor tracks my tablet pen, but it won't actually draw or erase. The first time this happened I restarted my computer and the program several times then let it sit for a while and it finally worked, but it's happened again and two days later I still can't do anything to the canvas. I've been working on this painting for a few months now and I'm supposed to enter it in an art exhibit soon so I'm pretty worried.
Is this happening to anyone else? Is there anything you can think of I should try?
