18 month old Toshiba. Windows 8.1. In the, last, few, days the mouse, has kept freezing/disappearing. Today it's lost, the plot completely.can't get into my talk talk emails in standard version as suddenly I have an.unsupported browser (it says). Can't see anything that involves java script or adobe flashplayer as apparently these have disappeared....what on earth? Have spent an hour trying to get into internet explorer tools to try and, resolve but don't really know what I'm doing. Any thoughts?
