When I want to comment on something someone wrote, I can only write a line when it jumps
Into another box and this next box has no label (SHARE) for me to get it posted.
I hope I'm clear enough.

If Ms. Jones writes it's cold out and I want to write she should take that trip to
Florida for the winter, I can only get on one line of info... that box says share
But it jumps down to a second box (which it should not do) and then there's no
SHARE to post it.

Delete you browser's history and all temporary files. If no luck then update the browser. If still no luck, download Google Chrome...

Hope it helps

Thank you for taking the time to reply. The problem has been solved.
