Light room not responding to mouse or click pad

[pamelamoi]

Hi 

I am using LR classic 7.1 with windows 8.1. Everything was working fine until a couple of days ago and it stopped responding to my mouse. It opens fine but does not close unless it's a forced close on shut dow. 

I can't open potos to edit and it won't open debvelop or library ? 

Any ideas please. I just paid my sub as well

Does the mouse cursor move?

Can you click on any of the menu items?

Hi 

The mouse pointer moves but it won't click on anything It just sits there. Not a full  page and won't close in the usual way.

Hi I have no clue what that is and I only have 2 lap tops one for home one for work, the work one is very basic an d ancient I don't have any editing on that and a basic older smart phone.
