I've just opened a page I deigned last week on a different machine (just loaded the software onto it). It looks fine, but when I try to select text to edit it each word seems to occupy its own text box. I'm used to using ctrl/shift/end for example to select a whole section, or shift/down arrow for a selection, or even that newfangled idea, the mouse, but none of these work. I can only select a word or two, and a red line appears under the selection. What am I doing wrong please?
