[comp.sys.mac] Mouse Double-Clicking Problem on MAC SE

jlc@atux01.UUCP (J. Collymore) (04/09/87)

I have run into a problem that is becoming a considerable hinderance in
using, and enjoying, some of my software and my MAC SE (dual-floppy).

Last thursday I got Wizardry by Sir Tech.  I noticed when moving through the
maze it would often respond with TWO clicks when I had only clicked on the 
mouse ONCE!  This caused me to do a lot of back-tracking and generally diluted
my enjoyment of the game.  I switched to using the keyboard for movement and had
NO double-click problems as I had with the mouse.  I was getting a double-click
~20-25% of the time.  I thought that it might be because of my installing the
newest System files from the SE into the Wizardry backup disk, but upon
putting the original older System Files back into my back-up I still had the
same problem, so I don't believe it's with the System files.  I did call
Sir Tech yesterday and asked them if it could be a bug in the software and
they said they'd look into it.

Then, last night, I was using Professional Composer and trying to create a
new score, and things started going crazy with erroneous double-clicking!
Two notes were appearing when I had only cliked for one (forcing me to waste
a LOT of time deleting notes).  Whole measures would sometimes become
highlighted when I had only meant to click on a single note!  This was the
first time I'd tried using Composer in a week, and it is the first time
since I got Wizardry and began having this problem that it's shown up in
Composer.  I have not dropped, nor otherwise mishandled the mouse, but I'm
really concerned with what's wrong.  I don't like spending thousands of
dollars on computer hardware and software and then not have it function
properly when I've had it LESS than three weeks!  

Could someone out there please offer some suggestions on fixing this
problem!

Thanks.

I should add that the double clicking problem has not shown up in Dark Castle,
Write Now, or doing anything on the desk top.

A followup to Jim Collymore about Macintosh SE double clicking:

	A couple of things to check:

	1. Check your control panel setting for double clicking.  Try making
	the reponse time longer.

	2. If double clicking continues, have the mouse looked at by a
	dealer.  It might be defective.

	As a general note:  The Macintosh SE had extensive testing for 
compatability (I know, I used to work in Software Quality Assurance) and 
the pattern of behaviour that you described is so bltant that it would have
been spotted.
	Also, while we are trying for zero defects in manufacturing (we are 
around 99% I believe), defects still creep into things.  That is why we 
place a warranty on our product.  If it is trully defective, please take it
to a dealer and have it replaced!

I also had a problem with extraneous double-clicking with the mouse on
my SE.  In fact, at one time I could hold the button right on the
threshold of being down with the mouse in the menu bar and watch the
menus flicker on and off.  This problem has since gone away, but I
thought it must be from dirty contacts in the button microswitch.
Maybe some contact cleaner would help?

By the way, other people have suggested changing the click speed setting
in the control panel, but I don't see how this could help.  When switches
bounce, the extra button ups and downs are coming very close together --
much faster than anyone could normally double click.  Unless I'm missing
something and the debouncing software also uses the control panel setting
to determine the time threshold for debouncing?
