Ok, so I created a custom XF86Config-4 using xf86config [working on
another issue]. and when I started using the custom config, the system
no longer opens apps twice. I have figured out the offending sections...
The original XF86Config-4 has two "InputDevice" sections. One for 
"Configured Mouse" [pointing to /dev/input/mice] and one for "Generic 
Mouse" [pointing to /dev/psaux], as well as two entries at the end in 
"Server Layout", one for each mouse entry. This is what is causing the 
double entries. It doesn't happen in my custom config because I only 
have one mouse entry. When I put the extra entry in my custom config, 
the problem reappears, so I'm 99.9% sure that's the issue :)
Now, I KNOW there is a way to have X deal with multiple mice when one 
[or more] of the mice are not always present. I had it set up like that 
on my laptop, so I know it is possible and that it does NOT cause this 
issue. Unfortunately, my laptop is currently deceased so I can't look 
and see how I did it.

If I find out for sure what method I used, I will post it to the list 
[and I guess I should post a bug.. ;) ]
