Over the last month, I have been having trouble with my mouse. The difficulty
is in moving it horizontally. The motion I now get on the screen is now
typically jerky enough to making precise pointing a nerve racking problem.
Sometimes, and this seems to take place when my office is below 65 deg, I
cannot almost not move the mouse in the right horizontal direction.

I am running 6.0.5 system software with 6.1.5 finder on a IIci with 16 meg of
memory (with maxima). I have two monitors: an Apple 2 page monitor, and an
Apple standard high res RGB monitor. I have the 256 capable board for the 2
page monitor, and am running the RGB monitor from the IIci internal board. 

I have changed the mouse and keyboard. I have swapped the logic board from the
ci. I have changed my mouse pad... Nothing seems to matter. Is there anything
in the monitor boards or the monitors themselves that would cause such a bad
mouse behavior?

Any other thoughts?

Thanks in advance,
