Every now and then my bluetooth keyboard goes mad. If I try to say type a word the word comes out in the wrong order on the screen and the cursor moves to the left v.quickly. Also if using any other application i.e word excel and I click on one of the drop down menus for example Help the cursor will move back to File at v.quick pace. The only way to resolve is if possible to shutdown the computer and start up, otherwise the only other option is a hard restart. Help
