Error in OSX

Hello All,

When I launch ipython (by typing “ipython -pylab”) and issue the first matplotlib command, such as simply “figure()”, I get the following error messages:

TkMacOSXDoHLEvent failed : cppe 1 ,kHighLevelEvent 44464458 0000 XDFD,-1708

TkMacOSXDoHLEvent failed : cppe 1 ,kHighLevelEvent 44464458 0000 XDFD,-1708

Any subsequent calls yield no problems. While this is not a show stopper, it is certainly annoying. Any thoughts on what might be causing the problem?

Thanks in advance for your assistance!

Chris
