I have also just discovered that if I do select the stack and copy all the data to a target measure, then select the target measure and hit "clear," stack related data does not clear. It has to be selected and deleted independently. 

It is also true that the stack related data will not clear from ANY measure, not just the target measure, EVEN WITH THE ENTIRE STACK SELECTED!

>> "F26 will not copy 'stack related data' (tempo marks, alterations, bar lines etc. that apply to the stack) unless the ENTIRE stack is selected."

No, that is NOT the way it has always been, sorry. I've been on Finale since 1996 and trying it again in ALL previous versions, including F25, it does not and should not work that way. Nice try.

This is confirmed with several of the composers and orchestrators I know and work with in LA. It is a bug. MMusic agrees it is not supposed to work this way at all.

Don't look at me... I got nothing.

Thanks Mike. I knew i could not count on you!  lol  F26 is also (intermittently) loosing the ability to attach articulations to rests. Not good if you have a fermata over a rest...  MakeMusic tech has been communicating with me, so that's a very good thing. I just sent them the file to test, but it DOES work properly in F25 and earlier, so I doubt it's the file. I've gotten confirmation of the copy/paste bug from other LA users I know who are testing the demo. They found other stuff they have also reported to MMusic.

… F26 will not copy 'stack related data' (tempo marks, alterations, bar lines etc. that apply to the stack) unless the ENTIRE stack is selected …

… not being able to copy data from a single measure, including bar lines and tempo markings, is truly untenable …

You probably mean “copy data from a single staff, including bar lines and tempo markings”, right?

This is possible, but you have to know the trick:

You must make a Stack Selection of that single staff only.

To do so:

First program a Staff Set of only that single staff. *)

Then, while viewing the new Staff Set of that single staff, make a Stack Selection of that single staff.

I just tried it in Finale v26, and it works for me.

For what it is worth:

It has been the same in my own versions of Finale v25, 2014.5, 2014 and 2012:

Make a Stack Selection of a single staff, and you can copy 'stack related data' from that single staff.

I could be wrong here, but I seem to recall that Finale has been working that way since Finale 2009.

I am not saying that you are wrong; it may very well also be possible in Finale v25 and earlier to copy 'stack related data' from a single staff without making a Stack Selection.

*) To program a Staff Set, first switch to the Staff Tool, and switch to Scroll View.

Then select the staff (or staves) to be included in the Staff Set.

While holding down Option (you ARE using Mac Finale, right?), go to

View menu > Staff Sets > Program Staff Set 1

NB: Staff Sets are {Scroll View Only}

Thank you Peter. This is not working. The score I'm doing now is just a piano score. I programmed the staff as described (yes, on a Mac and Finale for 23 years and remember you in the old forum days, so I know you know what you're talking about). ;)  I have never had to program a staff set to select and copy stack related data. Again, the copy paste feature works in the previous version of Finale up to F25, then it's gone in F26.

Clearly, there is something not working correctly here and I am not the only user seeing it. I really appreciate your taking the time to chart that out as well as you did. I was so hopeful that was the answer. I'll continue working in this problem over the next 2 weeks. After that, I'll be requesting a refund if the problem isn't resolved by then.

Bummed!

By The Way:

In a 1-staff document (like solo guitar) all selection is Stack Selection (= no need for a Staff Set).

But …

Why does it work for me, and not for you?

Did you follow J Adrian Verkouteren’s advice, and check the Copy Filter?

You probably did, but many users forget that they had enabled the Filter.

I have a slightly OT question regarding the Copy Filter. I have it always checked and adjust it when I need it for specific copying needs. I actually never realized that it could be un-checked. If it isn't checked what does it copy? The same as if checked and "All" is selected?

Yes, when the Copy Filter is de-selected, nothing is filtered = everything is copied.

I’m hearing from several folks that I’m wrong about the stack copy thing. Also, the edit filter clearly seems to indicate some aspects are only stack related. I’m 99% sure if I had a piano score and only copied the treble clef and pasted it elsewhere it would inherit all the data or alternatively what was in the edit filter.

That being the case, it would seem that F26 is working as expected. OTOH, that is not how things were working here before, so I guess what I was experiencing was a bug and it's been squashed. lol OK, I'll just have to accept that, I suppose and move on.

Other than that, F26 does seem to be working just fine.

Thanks for all the feedback and suggestions.
