I recently purchased a Speedlink bluetooth mouse for my Nexus 7. The Nexus searched and found it the first time and it worked fine.  Unfortunately, I discovered that each time the Bluetooth was turned off, I had to un-pair and re-pair the mouse every time to get it working.  The last time I did it, the Nexus found the mouse and put it in its "Available Device" list.  Pressing the mouse name, to pair it, no longer works.  Nothing happens.  Any ideas on how to fix this problem?  I have tried various routines and sequences without success.  The mouse works fine when connected to another computer.
