Geometry questions

Hello ROOTers,

I am writing a script which builds the 3D geometry of an array of multi-anode PMTs. Minimized script is attached in this mail. I have three questions about the script.

I am using SVN trunk on OS X 10.6.

Q1. After I close GL window, I get the following errors. How can I remove this error? What is the effect of this message?

llegalArgument: CGSGetSurfaceBounds
Tue Nov 30 16:58:08 dn0a20a279.sunet root.exe[41715] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged. Tue Nov 30 16:58:08 dn0a20a279.sunet root.exe[41715] <Error>: unknown error code: invalid drawable

Q2. When I run the script, MAPMTs' input window (transparent blue), photocathode (red), and other structure (black) are not drawn. But only the surrounding volume (TGeoVolume* mapmt) is drawn. However, if I uncomment the line 78, 151 MAPMTs are drawn as expected. ROOT cannot draw more than 151 MAPMTs in this script. How can I draw all MAPMTs?

Q3. The color of the first MAPMT is not black but light brown (see the attached GIF). What does this indicate? any error exists?

Regards,
