This problem started occurring recently When I finishcopy and pasting in Open Office document and then hit ENTER often a dark double line appears and several if I hold down the Enter key too long. Then I have to go to EDIT on the Menu and Undo, but I can't move down to enter something else without it happening again. ; . This is so annoying because I will use lot of ink when I print out the document. It doesn't happen in evefry Open Office doc that I open. Has anyone experienced this? Thanks for any6 thought how to stop this. Joan
