[vtkusers] TkRenderWindow Problems

[Erik Sobel]

Has anybody had the following problems with the vtkTkRenderWindow?

1) Crash when I close a tcl app which contains a vtkTkRenderWindow while 
the app is minimized (this is on WinNT vtk 3.1.1).  It exits ok if the app 
is not minimized.

2) Crash if I remove actors from the renderer and then exit the app.  It 
exits ok if I RemoveActor and then AddActor it back.  If I use a regular 
vtkRenderWindow instead of the vtkTkRenderWindow I can add and remove 
actors all day without this problem.  It is also necessary to call renWin 
Render after RemoveActor to get it to crash.  If you don't render, it 
doesn't crash.

The crashes are access violations ("Attempted to access memory blah blah 
blah...").  Am I supposed to handle resource allocation and release 
differently when using the TkRenderWindow?

Thanks,
Erik
