I think I posted this before.  I use two monitors and it does not work.
Monitor 1 on the right is the primary monitor (a notebook).
The resoultion is 1600x1200.
Monitor 2 on the left is the secondary monitor, which is 1280x1024.
To be short, all of the x-windows can only repaint correctly if they 
were totally within
1600 pixels starting from the left-most end of Monitor 2.

In this new lab of mine (which is very rich....) even the students have 
two monitors.
I am going to teach them C++ since June, and I shall ask them to install 
cygwin....
I hope that by that time they will not be puzzled by this behavior of cygwin
on dual monitors.
