Can’t edit the “Text” widget because title is too long

This is a new one to me. In this particular instance, the title I used in the text widget for the right sidebar was just long enough to run to a second line. I didn’t like the look but when I went to edit it, the little “edit” box is not accessible because the “too long text” makes it disappear.

At this point, it seems I’m stuck. I cant’ edit it – I can’t delete it even so I can recreate it – it’s just on my site with no way to change it in sight.

Thanks, in advance , for the help.
