4R6 - Click Draw menu = crash

4R6, Mac OS X (10.6.8)

I seem to be able to crash Zbrush pretty consistently during a session simply by clicking on the Draw menu.

Dialog says something like: “Failure to read vmem”. Click okay -> crash.

I’m trying to troubleshoot to see what might be causing this.
Anyone else having this issue?
