Please excuse me for reposting. When I write in the Add New Post field, the text continues over through the right hand sidebar (where the Publish, Tags, etc. fields reside). When published, the blog is fine. This seems to happen with any theme.
This just started to occur with the 2.7+ versions. I don't have any problems with my display adapter or any other software or hardwar issues.
Thanks for any light anyone can shed.
