I could not reproduce your problem.
I did try to save the TCanvas with "Save As" menu and via
SaveAs method as well. No problem so far.
The simple thing I may suspect is the DLL mess. I mean you did
not recompile ALL your sources against of the new version of ROOT
for example I have old version of the ROOT include files on your INCLUDE
path by some reason of your MS project still keep the old ROOT include
files in.
Please check this first. Make sure you have no old version of ROOT
around.
Just another guess. The compilation parameters were changed (?)
by ROOT team those your not aware about. ROOT team switched from
CMZ to CVS / makefile and this may cause many confusions now and
in future.
