mouse wheel not working with xterm

[jose isaias cabrera]

Greetings!

I am running cygwin with xwindows (XWin) and none of the xterm history is 
accessible through the mouse wheel.  I have a IBM R50 laptop, which has a 
touch wheel on the right side of the touch-mouse.  The touch mouse works 
perfectly, but the touch wheel does not.  I have another laptop (compaq) 
with similar touch mouse/wheel options that is working ok.  Yes, the mouse 
work perfectly on the MS Windows XP base.

Any ideas?

thanks,

josé
