I thank all of you for your suggestions , however i`m a computer nerd and well into my 70`s which does not help.
My mouse is a logitech plugged into my harddrive ? no batteries .
When I have the problem I turn off the pc unplug it from the wall and unplug the mouse from the harddrive ?
which has fixed the problem until next time it happens and I do it all over again.
Maybe I`m a lost cause.
Simon ," How would your mouse dying make you lose what you have typed ?" Easy , .no cursor , no control .
I would love to know how to control my pc with just the keyboard but I am afraid it may be too complicated for me.
