[comp.sys.ibm.pc] My Logitech HiRez mouse jumps to the right! hop! hop! hop!

mark@motcsd.UUCP (Mark Jeghers) (06/29/89)

When I move my Logitech Hi-Rez mouse to the LEFT, it does so, but it
intermittently takes jumps back to the right as it moves.  I've seen the
mouse work flawlessly on other systems.

I have an AT clone.  It has a Hercules/parallel port card (may be a
clone card), and a floppy/hard disk controller.  I had a multi-I/O card
which seemed to conflict with the mouse's interrupts (the pointer would
FLY to the right and stay there).  I have taken that card out, and now
the mouse works okay except for the intermittent jumping.  The multi-I/O
card may have been for XT's only... 

The jumping sometimes lessens in frequency after the system has been on
a while.

Where can I go to find out what is causing this?  It is probably an
intermittent spurious interrupt from something else.  But what???

Thanks for any and all help!
