Another Posting Issue?

I was unpleasantly surprised this morning to find the size of the comment box has shrunk again at least on my Mac and i Pad.  They shrunk it vertically a few years back and this time it is has been severely  shrunk horizontally. Has anyone else discovered this?  It seems to be just about the size of the comment section on my i phone. Here is hoping it is just another glitch that will clear up.
