#68 samples\wx\Print.hs: window disappears when a menu option is selected

[Henk-Jan van Tuyl]

The sample program Print.hs crashes when File/Print a test, File/Print preview or File/Page setup... is selected

OS: Windows XP
GHC version: 7.6.3
wxWidgets version: 2.9.5
wxHaskell version: 0.90.1.0 (currently in Github repository)

This still happens for File/Page setup...
The option "File/Print preview" results in a window with the message:

wxWidgets Debug Alert
../../src/common/object.cpp(417): assert "Assert failure" failed in CreateRefData(): CreateRefData() must be overridden if called!
Do you want to stop the program?
You can also choose [Cancel] to suppress further warnings.

Current configuration:
OS: Windows 8.1
GHC version: 7.10.2
wxWidgets version: 3.0.2
wxHaskell version: 0.92.0.0 (currently in Github repository)
