[vtkusers] Resource forking problems on Mac with python and vtk

[Alethea]

I am running vtk 5.0.3 compiled on Mac OS 10.4 and python 2.3

when I start up vtk examples, the window does not come to the front, 
cannot be selected, and all keyboard messages go to the command prompt 
instead of the window. As a result I also cannot even stop the process 
without killing it in the command prompt.

I have found some information about Mac resource fork issues, and using 
'Rez' for compiled programs, but cannot seem to find anything about how 
to fix this problem in a language like python.

Any help/pointers would be greatly appreciated
