Hello, I've tried 3.8.6 (as it's the most stable for me) and this almost doesn't happen at all). I had it twice in an hour or so - I was using the eraser and then changed some settings (opacity, IIRC) in the brush editor and the eraser randomly changed to a blur brush that I'd used three tools prior on the pen tip, rather than the eraser tip.

It did let me change it to the eraser again. Again, this is a bit random still and I don't seem to reliably make it happen, sorry. :/

Thanks for the link, though! When I googled Mypaint I got http://mypaint.intilinux.com/?page_id=6 where the version is much older and doesn't have a lot of tools! It's really enjoyable to use on this particular version. :)

Have you tried with TumagonX's latest builds?

I'm using MyPayint on Windows 7 with an Intuos 3 tablet with the latest drivers for it.

Steps:

- Start up MyPaint;
- Choose either of the brushes in the summary (I've not installed additional ones yet, so you chould easily find them) and the CDconcept/eraser for erasing;
- Start drawing and switch between eraser and brush normally, change some parameters from the * menu at the top as well;
- Check something on your browser, which will take focus (I use Chrome);
- When going back to Mypaint, go straight to erasing (with the eraser on the pen), don't start with the drawing tip of the pen.

Results:

9 times out of 10 I wasn't able to erase, the eraser would function like the brush or pencil I had selected at the time. I had that happen with another eraser as well, but I don't remember it's name - I do believe the brush and pen selected at the moment are irrelevant to reproduce it.

The only time I didn't manage to reproduce this was when I tried straight after restarting MyPaint and I simply started drawing, checked Chrome and then went back following my steps (minus the changing brush size and opacity) to try and give a reliable repro.
When I then kept drawing thinking it might have been a fluke and changed brush, but not the eraser, it happened again.

Setting the eraser end of the tablet pen back to an eraser tool usually works, but in one case MyPaint was just refusing to cooperate and whichever tool I set for the eraser would be fixed on the pen as well, forcing me to restart it, which solved the problem.

Sorry, I can't seem to give you more exact steps than this, but if there's some tool that I can run to help you find out why this happens, please let me know.

Thanks in advance for any input!
