I don't think any of the above topics relate to my question. When I am typing an email (AOL), I type for awhile and then all of a sudden, the cursor just disappears. I have to point my mouse again and click to get it back. Then I type again, and all of a sudden it again disappears. I have read articles, etc. but nothing seems to help it. What is the problem and how do I fix it? If I switch to a different browser there is no problem; only in Firefox. Thanks, Kathy
