Horizontal Adjustment Malfunctions 2.2.20

Has anybody experienced this?

Dorico is allowing me to adjust some handles, but not the major margin handles in engrave mode. I’ve tried closing the project and reopening but no luck. Thoughts?

Per this thread, pictures and videos unfortunately don’t allow problems to be efficiently diagnosed.

My apologies for not attaching the project. I’ve emailed it to you directly, Daniel.

reply from Daniel: there was indeed a bug that has already been quashed in current development builds and will be resolved by next release.

If anyone else experiences the same, he suggests using an additional music frame just for the affected lines.
