[Dev] Chandler pegs CPU

[David Surovell]

John,

Yes, that's familiar.

I remember that I could make the problem occur in the wxWidgets 
"widgets" demo when there were more notebook tabs than available display 
space.

So why is this happening now? Is there enough room in the markup bar to 
display all 5 tool icons?

Regards,
David S.
