Hello,

  I have been working on my new Debian 10 machine trying to get things updated 

and installed for a work machine.  I noticed the other day my center mouse click

would not paste the contents of a highlighted text.  It will copy and right click paste,

 but not left-click copy, center mouse roller paste to anything.

What happened?  How do you fix that?

Never had this happen before.

thanks,

Greg
