[Bkchem-user] Cmd-C (copy) on Mac OS X causes application not responding

[Bruce]

Hi,

I'm running bkchem (both stable and 0.14.0-pre2) on a Mac running 10.7.2
(Lion). If I click on the menus (either within bkchem or at the top
(python) menu to get Edit... Copy, then all is well. If I hit the
keyboard shortcut Cmd-C then python becomes "Application not responding".

Running bkchem.py from a terminal and hitting CTRL-C when it is not
responding produces this backtrace below (hopefully helpful?).

Is this a known bug with a known workaround (apart from don't do that,
the old brain is incapable of learning not to press Cmd-C for copy)?

Or is there anything I can do/change/run to help solve this issue?

Regards, Bruce.
