I have several websites that I have developed and I've upgraded them all to 3.0.1. A big annoyance is the Page content text box is not very tall. A new site that I've been working with which was installed by someone else has a stretch corner in the bottom-right. My sites don't have it. I asked them and they don't believe they did anything to allow that.
I'm working in the same browsers (IE8 and Firefox).

Can someone help de-mystify this for me? Am I missing some setting? It seems this should be a standard thing.
Thanks so much for your help.
