I use MS's Office 2008. MS no longer supports it, so I'm hoping a knowledgeable Word user here may be able to help. I have a problem with Word when revising a draft document. After resuming typing following a pause, the cursor will often jump ahead to a random position and insert the text I'm writing. The same can happen when I back delete: the cursor will jump back somewhere and delete the text there. But if I remember to click on the cursor first (as though to reactivate it or confirm its position) it doesn't jump.
