Hi rooters,
in our online-monitoring framework for CDF, we want to put TCanvas objects in
a TMapFile and save them to a ROOT file at the end. Unfortunately the TCanvas
objects in the ROOT file cannot be drawn in a ROOT session:

Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] TFile f("test.root")
root [1] CMUDCanvas.Draw()
Error in <RootX11ErrorHandler>: BadAlloc (insufficient resources for operation)
(XID: 96469120)
Error in <RootX11ErrorHandler>: BadDrawable (invalid Pixmap or Window parameter) (XID: 96469120)
Error in <RootX11ErrorHandler>: BadAlloc (insufficient resources for operation) (XID: 96469121)
Error in <RootX11ErrorHandler>: BadDrawable (invalid Pixmap or Window parameter) (XID: 96469121)
and so on...
I have reduced our code to a little program, that I will attach to this email.
I hope anyone knows, how to remove this problem.
Thanks a lot,
Hartmut.
