Not possible to select noteheads by type (normal, cross, Mi etc.)
(Win 7 HP. MuseScore 2.0.2 official). Came up in Support and bug reports .
The crosshead notes in the attached score do not select at all when you right-click on one of them and chose select > more …. It doesn't seem to matter what combination of selection criteria you use: nothing is selected.
Apparently the result of a previous bugfix. See this link:
