[vtkusers] Tcl object disappearing

[Martin Saturka]

Hello,
time ago I posted some messages on object disappearing.
It is in Tcl wrapped mode (it is OK under C++ direct
compilation). It is so inside vtkBoxWidget. I use VTK
4.2, Tcl 8.4, Debian/Linux.

The bug can be viewed at tutorial Cone6.tcl example.
Since C++ version is OK, it is not caused by videocard.
I do not know what to do with it.
