Man, this is fun!  You are so quick.

First of all, I wanted to let you know that Qt# compiled with cscc gives the 
following error when run with mono:

Unhandled Exception: System.ExecutionEngineException: file codegen-x86.c: line 
6333 (mono_burg_emit_261): assertion failed: (tree->data.i > 0)
in (unmanaged) 00 Qt.QNull:get_Instance ()
in <0x00010> 00 Qt.QApplication:.ctor (string[])
in <0x00032> 00 QtSamples.HelloWorld:Main (string[])

Now, onto pnet :-)  I've updated cvs and now this is the error I receive:

Here is the trace:

*sigh*  We have been having so many problems with our Disposal code and 
implementing IDisposable with Mono.  Rhys, do you have Qt# installed?  You'd 
need Mono to generate the bindings (apparently pnet's System.Xml can't run 
our generator yet.)  Thank you for all your help Rhys.

Cheers,

Adam
