If you hit "OK", another one follows:

Sometimes that is followed by a much simpler error message box exclaiming a Python script error.
After dismissing the error messages, the paintbrush will often show up, but it behaves wildly. It's prone to disappear and won't come back unless I hold alt and zoom in and then out (super weird). Crazy stuff also starts happening to the rig/skin:

Nothing special about the node network either ... this seems to occur with every character I've tried, every scene, even a fresh one with 3rd party models downloaded from online and directly wiring things up.
Painting weights is really difficult due to these erratic behaviors. It doesn't paint correctly. It seems to keep switching to "Smooth" operation of its own volition, and using Ctrl/Shift modifier keys doesn't have consistent behavior. Sometimes it will erase, sometimes smooth, I have no clue what's going on.
Would really appreciate some help with this. I have always hated painted skin weights and had bad experiences with it in every software. At least this has been the least bad experience, despite the crazy buggery. But still far from enjoyable or pleasant, haha. It's honestly a major game dev show-stopper :-(
Before I make an official bug report about this, I wanted to check and make sure that I am not doing something wrong or overlooking something obvious, and see if anyone knows a work-around or alternative so I can get this work done!

Aaron
