NO problem here with "Everett".
Since no steps were provided to try to reproduce, the following test procedure was created:
1. Turned off Snap to Grid.
2. Used Smart Tool to draw 6 quarter notes in the PRV at various distances from the grid.
3. Enabled Snap to Grid, "Snap To", and Whole note resolution in the PRV after verifying Global Snap was enabled.
4. Selected all 6 notes.
5. Used Smart Tool to grab the 3rd quarter note and dragged to the right. All notes moved as a group until the 3rd note approached a measure grid and it snapped to the grid with no problem. The remaining 5 notes moved the same distance as the 3rd note, but did not "snap".
6. Repeated Step 5 for each of the remaining 5 notes with the same results.
This is the expected behavior, since only the note that is grabbed by the mouse in the multiple selection will "snap".
Also tried the above steps in Sonar X3 with same results.
Were your steps any different than mine?
