>Description:

using a second mouse and then pasting causes 3-button emulation on the
first mouse or trackpad to stop working.

>How-To-Repeat:

1. start X11 on a laptop or some device that has a 2-button mouse using
   3-button emulation. note that pasting and similar third button function
   works fine.

2. plug in a second 3-button mouse. note for the moment the third button
   function for pasting continues to work.

3. use the second mouse to perform a paste with its third button. notice
   now that pasting with the first 2-button mouse no longer works.

>Fix:

none
