remote Mathematica client does not work properly in Cygwin/X (pointer bug?)

I'm using the latest Cygwin/X for Windows XP.
I use xinit to start X server on my local computer,
then connect to a remote linux computer by 'ssh -X'.
Many clients work properly, i.e. xemacs, mozilla, etc.
However, the pointer does not work good when I start
Mathematica(V5) on the remote linux computer. 
The error information is, 

X Error of failed request:  BadWindow (invalid Window
  Major opcode of failed request:  38 (X_QueryPointer)
  Resource id in failed request:  0x3a
  Serial number of failed request:  23406
  Current serial number in output stream:  23406

As long as I move my pointer to any Mathematica
window, that error message will appear on the window
where the Mathematica is started.  
The Mathematica can not recognize 'Shift-Enter' 2-key
Usually, the Cygwin/X crashes after I use Mathematica
for a long time.

I don't know if somebody else has also encountered
this kind of problem. 
Please help to solve this problem.
