Dear All,
I would like to draw (3,3) subplots and afterwards resize the whole widget.
Plotting works like a charm, but when resizing the widget these errors are
reported:
(Version 0.87.2, Tkagg,suse 10.0)
When resizing, or even just clicking on the button for the widget to rearrange
the plot on the fly, I get the messages below...
cheers Juergen
PS I am currently using the figsize option to figure as workaround..

Juergen,
I think the patch below will fix the bug; I will apply it to svn unless a problem crops up.
