strainge problem

I have an excel xp application in my network
it works fine on many new stations but some of the Pentium
II stations there is a strainge thing occure
when the user click at any cell in the worksheet then if
he want to move to another cell the mouse will be move to
the other cells as if you make drag and drop and stay as
if clicked for ever and no termination to this process
unless you make Ctr Alt Del to end task from task manager
the strainge thing is this problem is on nearly pentium 2
stations .any idea will be appriciated.

happen if their accounting application is open also.
It has happened with Solomon and Macola.
If anybody knows how to fix this, please email me.
I have the latest updates for Office XP.
