3.4 RC: Barlines applied from palette by single-click, instead of double-click
OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 18.104.22.16862, revision: 716655c
Barlines are now applied by single-clicking from a palette, rather than double-clicking as before. Assuming this is an oversight, given that it breaks the double-click rule for all other palette components, and increases the possibility of user error.
