I don't see that here (although I am using Finale v25).

How are you entering the notes? Mouse? Simple Entry?

How are you moving to the next measure? Clicking to add a new note? Arrow Key?

Can you post a screen shot of your result? Are you sure that the rest is in that measure, and not in the next one?

Thank you for your replies. I enter the notes using the mouse in Simple entry. I click to add the next note. I've done my best to save a screenshot but am completely unfamiliar with the snipping tool and though I am following instructions, it doesn't do what I want it to. The rest is definitely in the measure. I'm wondering if it is a bug that was cured by an update.

1. In Simple Entry I typed the quarter, and then another quarter which I turned to a rest (the "r" key).
2. Then I typed another quarter and pressed the "9" key to turn the quarter into the first of a triplet of quarters.
3. Then I typed additional quarters on top of hte two rests under the triplet sign.

That's not the only way to do what I did above, but it is one way, and it works.

Adrian is, I believe, using the ABCDEFG keys on the QWERTY keyboard to enter notes, which is also my preferred way. If you do that, his instructions should work perfectly, as long as you have your default triplet set for either 3 use current in the space of 2 use current, or 3 quarters in the space of 2 quarters.

Actually I set the pitches with mouse-clicks. I normally use a MIDI kbd (and Speedy Entry), but for this short example it wasn't worth turning the keyboard on.
