ADDITIONAL INFORMATION
The error occurs infrequently, probably less than 1% of times the tool is used,
but often enough to be a daily occurrence, multiple times per day in fact (in a
6 hour drawing session I can expect 3-4 crashes on an average day). Anecdotally
it seems more likely to occur if the program has been open without being used
for a longer period of time, but can also happen shortly after the program has
been opened. This bug has been consistent across numerous versions of the
program, at the very least in both versions 4 and 5.
