Unless someone has turned off the handles, you should see two of them when you apply the articulation.

I don't get those options either. Frustrating, because the rolled chord instructions don't behave like it states.

Just for the heck of it, check these settings in Preferences.

Yes, those settings are current.

I just tried it in a brand new file to make sure it wasn't a corrupt file. I click "shift-R" and the rolling chord is highlighted in a popup menu. I press "select", and click on the bottom note of the chord. For some reason it won't let me pick the lowest, so I picked the second lowest. Then when I let go of the note, another symbol appears (square bracket pointing down, not familiar with that symbol.

Hi Stephen,

That isn't right. Shift-R is to ASSIGN the shortcut key. You pressed sh-R, then selected the Roll and hit Okay (it was probably already assigned to R). The next step is to hold down the R while you click your chord. Then next time you want to enter a roll in this document, just hold down the R while you click the chord.

Alternatively, if you don't know the shortcut (called "metatools" in Finale-speak) you click the chord and manually select the roll articulation from the window. I think that's what you were trying to do, but got it confused with the metatool.

Ah, holding R down works! Thanks. This doesn't work, so I hope someone fixes the manual:

I could not get it to work from the articulation window. But this work-around gets me moving again. Thanks again.

p.s. For some reason, in the older file it doesn't display both handles (upper is missing), and when I try to move it, it snaps high and low. So maybe that file is corrupt?

How old is "the older file"? That could make a difference.

The "older file" is actually only a couple weeks old, created with version 25.1 on Windows 10.

Very puzzling!

I've had other troubles too. Maybe I should uninstall the software and start over from scratch. Yesterday I finished up another file, and printed to PDF file using the Microsoft Print to PDF printer. Measures moved from one system to another. But printing the same file 2 minutes earlier using CutePDF Writer didn't. There have also been a bunch of other buggy features.

To be honest, I'm seriously considering jumping ship to Dorico, even though it sounds like their software doesn't yet support some basic features. At least they seem interested in supporting and fixing their product.
