Hi John,
My apologies for apparently missing your earlier response.
Interesting enough, last night when i was looking around in the
backend_wx.py code for what might be causing those debug messages,
i thought that line:
> wxInitAllImageHandlers()
in conjunction the "Adding duplicate image handler" looked
suspect. I briefly thought about commenting it out...but i
figured that would probably break the tool bar icons etc.
As you suggested, i tried commenting that line out, and sure
enough: no debug messages...and my app that does some plotting
appears to work fine.
Thanks a lot!!
Glad my report led you to a problem you were looking for.
Jim
