Fwd: xfce, Apple X11, and mouse emulation

[Fred Dushin]

I was wondering if anyone one this list might have some guidance for  
diagnosing this issue, as I don't think the macports folks have any  
insight into the problem.

For the benefit of the XFCE crowd, I am running XFCE 4.2.2 on an  
intel macbook (core 2 duo), built off macports (http:// 
www.macports.org).  I have been able to confirm the same behavior on  
a PowerPC, so it does not seem to be processor-related.

Thanks in advance for any pointers.
