WIN64 windows unresponsive
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Under WIN64, windows for example programs such as RGrid do not update themselves, do not respond to input, and do not cause the application to exit when closed.
This is due to truncation of 64-bit pointers and insufficient allocation of extra window bytes. A patch is attached.
The same bug appears to be in other files, e.g. the vtkTk* files (untested).
