Howdy,
You can still select the brace/bracket, but it is a more "picky" than previously. The following tips should help:
1. Zoom in on the score, so that the brace/bracket is larger.
2. Click and drag across the bottom of the brace/bracket - this usually will "pick up" the brace/bracket, and thereby select it.
I apologize for the inconvenience, and it is on our "fix it" list.
ttfn,
Sherry
