[vtkusers] Selection offset from mouse

[Eric E. Monson]

Hello,

I'm noticing a strange problem where selections in a vtkRenderWindow  
are offset from the mouse position. (OS X 10.5.5 Carbon and CVS VTK --  
don't see it with OverView or ParaView.)  I notice this most with the  
Infovis graph view examples because a rubber-band selection mode is  
part of the default interactor, but I can also see this in examples  
like Annotation/Tcl/annotatePick.tcl

The selection is offset from the mouse by the same amount as the  
render window upper left corner is offset from the upper left corner  
of the screen area (right below the menu bar). Here are four screen  
shots where you can't see the cursor, but I have dragged the mouse  
over the _same_ are of the window -- I started my selection in the  
upper left corner of the render window and dragged to the black dot  
near the center. Notice how the selection rectangle is offset  
differently depending on where the window is placed before I do the  
selection...

Anybody else ever see this? Any ideas?

Thanks,
-Eric
