Dear Rene,

I just tried the macro. 
When I point the mouse on the boxes it remains the "+" sign so I can not 
rotate it in the usual canvas. 
It perfectly rotating in X3D and in OpenGL. But what really surprised me 
that if I start in the same session OpenGL after finishing X3D or vise 
versa - the segmentation violation is happend:

FreeType Engine v1.1 used to render TrueType fonts.

CINT/ROOT C/C++ Interpreter version 5.13.92, Mar 13 1999
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] .x fitz.C
root [1] Total size of x3d primitives:
     gSize3D.numPoints=1600
     gSize3D.numSegs  =2400
     gSize3D.numPolys =1200

 *** Break *** segmentation violation

X3D and OpenGL were started from "View" menu.

My system parameters: 
RH5.2  gcc version egcs-2.90.29 980515 (egcs-1.0.3 release)

Root was compiled from src, but I didn't observe any singularities in 
the tests and tutorials so far.

What could be the reason of the problem?

Best regards
Valeri
