Can't reduce part size in last system

[voulalas]

I have figured out how to reduce two parts in a trio, for the piano score. However, in the last system the two part sizes are the same size as the piano part, and I cannot seem to reduce them using the standard approach (Page Layout > Reduce Staff System, Select Parts, etc.). I searched here and elsewhere, but can't find a solution.

I tried to attach a screenshot here, but it says that the file size is too large (at 330K???).

Thanks in advance for your assistance.

Try the Resize tool rather than the Page Layout tool.

Thank you, Motet, that worked. I did look into that approach earlier, but because I couldn't select specific parts to reduce, I thought it wouldn't work!
