>If the caption is long, almost fills the entire button width, this works perfectly. If the caption is short, such as one word, I get the 1 and caption on the same line with a small outline square between them.

Ah, I remember starting this in Thread #337151, and I see exactly what you mean. Well, I imagine part of your caption is dynamic and part is static? You should pad the static part with empty spaces on both sides so it is both centered, and long enough to force WordWrap. Does this help?
