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 at fine@bnl.gov > *** TGWin32PixmapObject: Create Bitmap error - 8 0 With my best regards, Valery ----- Original Message ----- From: Matt Fritts <mfritts@physics.utoledo.edu> To: <roottalk@hpsalo.cern.ch> Subject: unknown TCanvas problem > Hello all. > > I've been running Version 2.22/10 for NT for a few months.
