Happy to report that this problem has been solved. After weeks of trying, I tested a new bluetooth mouse and found it worked correctly, as the previous mouse did until it broke down.

I used a bluetooth mouse from then on and never lost contact between computer and mouse, not even when changing the battery in the mouse. Since installing 1404LTS Beta 2 the connection is shut down when the computer is shut down and sometimes when the computer goes into hibernation. This results in having to manually goto the Bluetooth GUI and the mouse and force the connection. The Bluetooth GUI has three on/off buttons, bluetooth , visibility on Ubuntu-0 and mouse. The mouse button is off wenever I start the system. This did not happen in any Ubuntu version of Linux I have had on this computer, other than in 14.04LTS. This is a nuisance, and prevents me from demonstrating how good Ubuntu Linux really is. Having to sit in a demo and manually pressing a button on the mouse until the on/off button turns on immediately turns off any interest a newbie might have. A quick fix would be appreciated. At this point I have no idea od what corroborating info I need to provide, but will send anything asked for.
