Short description of error
After a short period of sculpting, i want to mask and when i do so it closes.
Exact steps for others to reproduce the error
make some head shape, reshape, grab the mask tool with B or Mask brush an then it closes.
[Based on the default startup or an attached .blend file (as simple as possible)]
