Hello Matt Fritts
I was unable to reproduce your problem.
It seems to me it has nothing to do with the number of TCanvas's
I was flooding my screen with number of Canvases and met no troubles
(but lost myself between those canvases ;-)
I wonder there is another reason within your code.
Could you supply further information to me directly

With my best regards,
Valery
