One of our staff is having problems with his keyboard. In the middle of an operation (Outlook, Word, Excel) multiple areas start to be highlighted. In Excel, as he moves to each cell, all cells moved to become highlighted. In Word, whole paragraphs are highlighted. If you type anything, the remainder of the text is erased. If you right click, some of the highlight is turned off, but again highlights when you move the arrow keys to the next word. The same is true of Outlook. Also, it seems that cap locks works opposite of how it should; when turned on, all is lower case; when off, all is upper case. I went to the control panel to check settings. When I click on ‘keyboard’, all control panels from Accessibility Options through Keyboard were highlighted and tried to open. I checked the ‘sticky’ setting in Accessibility, and it is turned off. It seems like the ‘shift key’ may be stuck. But he has a laptop with an attached keyboard. Both keyboards act the same. The problem seems to go away without any logical sequence. Any help would be appreciated.
