[Pyobjc-dev] Fwd: Memory leak, but only in a plug-in?

[s s <li...@in...>]

Barry,

	Could you please attach the new, improved version of the demo to the  
original bug report so any interested party can quickly see the  
problem.  The first compilable one you sent me shows the problem the  
best, I think.

	Instructions for using Instrument to show the problem might be handy  
too if you've got time.

Thanks,

S
