Here are the results for button push and release.  There was only one of 
each of the events logged.

After doing some more searching I found that people using Eclispse were 
have problems with menus. The fix was to start it like this:

env UBUNTU_MENUPROXY= eclipse

I tried it with gedit and it worked, but when I tried it with Firefox 
and Thunderbird it had no effect.

What did fix it was turning global menus on in the panel, but I hate 
global menus.  I had them turned off with no ill effects in 12.04. I 
guess I will have to keep experimenting to find a solution.

Thanks,  Jim
