Summary: inadequate debouncing in the Lisa?
Apparently-To: rnews@mcvax.LOCAL

Has anyone else experienced problems with the mouse of the Lisa (used
as Macintosh/XL with 10 meg internal hard disk under MacWorks 3.0)?
When the machine is on for an hour or more, almost every click is
turned into several short clicks.  Very annoying, since dragging an
icon in the Finder has over 50% probability of launching an
application!  (Similar problems with word selection in MacWrite.)

It seems that the mouse button's switch is not adequately debounced by
the Lisa hardware.  I have suspected the mouse, but the same mouse
worked fine with a normal Mac, and the mouse from that Mac gave exactly
the same problems when attached to the Lisa.  So it's probably the
Lisa.

Does Apple know about this problem?  (Our dealer certainly doesn't know
what to do about it at this moment!)  Does anyone have a solution
(perhaps adjusting a potmeter inside the Lisa)?

As they say, thanks in advance, I'll summarize to the net, don't
followup but reply, I love mail, and "happy Mac'ing!"
