Summary: Work-around: mouse swapping.  Not all mouses are equally bad.

I have received several replies to this, some saying "my Lisa's mouse
also bounces", some saying "you just have to get used to the different
feel of the mouse on the Lisa", some saying "I don't have this problem".
(I don't think I could be asked to get used to it: I was unable to move
documents in the Finder because an application would always launch :-)

The most useful letter(*) told that, though it is probably really a Lisa
hardware (?) problem, it can usually be solved by "mouse swapping".  While
all mouses work fine with the Mac, only some of them work adequate
with the Lisa, so you have to find a Mac whose mouse the Lisa likes.
The original Lisa's mouse can then be used by that Mac with no problems.

In my case the first mouse swap I tried solved 95% of the problems;
very short clicks still have a chance of bouncing, but holding the button
down for a few tenths of a second makes it absolutely reliably.

Still, this is a problem that should really be solved in the Lisa
(I don't know if MacWorks or the hardware does the debouncing).

Happy swapping!
