I have a long vertical line (about 4 times the length of the text cursor and about 3/8" to the right of the text cursor) in fields that I would normally enter text. I have tried all of the control panel settings that I think would affect the cursor like themes and mouse pointer settings. This is my wife's computer and she told me that it started doing that a few weeks ago. I am not aware of any new programs except the usual Windows updates and anti-virus updates.
