[Chimera-users] Chimera crashes on Mac OS Sierra (10.12)

The Chimera developers have received 8 Chimera crash reports on the new Mac OS Sierra (10.12) somehow related to scrollbars. You may want to hold off updating to Sierra if you make heavy use of Chimera. We have not yet been able to reproduce the crash. It is very likely a bug in the Mac Tk window toolkit that Chimera uses, so even when we figure out how to reproduce it it may take time to figure out a fix since the problem is not in our code. Tom
