...which asks a question that has been bugging me. How to get those HUGE time signatures on printed tab back down to normal size? And here's what I've found, I think & hope.
While you have a print preview going on, click on "page setup," then "fonts." Highlight the "Graphics:" line, which shows the style & size (which for me was, I think, 84 point). Then click "change font" and select a more civilized size. 14 seems nice. The click ok, ok... until you're back out.
So far it SEEMS to be remembering this for all files, even in a new session.
