[vtkusers] vtkInteractorStyle::OnTimer causes hang

[Robert Wohleb]

Hello,

I am new to VTK, so bare with me. 

I am trying to use VTK inside of wxWindows(wxGTK). I am using the wxVTKWindow class created by David D. Marshall & Brian Todd. Everything works except for the occasional hang. This isn't just my app freezing. It freezes X entirely. I am able to get X back by logging in from another machine and killing my app. While tracing my app it appears to hang in the call to vtkInteractorStyle::OnTimer(). It doesn't always hang in OnTimer(). When I kill my app, though, it displays other debug messages with timestamps from the same time as the freeze ( see below ). Any ideas?
