Summary0009079: Erratic behaviour of time signature markers + crash
Description1. jumpy, erratic behaviour when left dragging time signatures
2. with a BBT the real crazyness begins
3. a crash can also be seen when manipulating both time signature and BBT
Steps To Reproduce1. create a new time signature marker
2. left drag it to the right and watch it jump immediately to the next bar
3. continue dragging, this time to the left. It will jump immediately to the previous bar

Looks like moving to a next or previous bar is coupled to the mouse direction. This behaviour makes it very difficult to manipulate. Note that dragging the tempo marker has more stable behaviour.


With a BBT:

1. create new time signature marker, at bar 4 for example
2. create new BBT marker with bars:beats 1:1, just after bar 8
3. left drag the time signature marker to the right of the BBT marker
4. watch it jump to BBT+8
5. draggin the time signature is now confined within the BBT marker (unless steps 8-10 are executed)
6. drag the time signature back to the left of the BBT marker
7. watch it jump again to BBT+8

8. move it back to the right of the BBT marker, more specifically to bar 2 within the BBT marker
9. move it a tiny amount to the left and watch the Bars:Beats ruler reset itself as if there was no BBT at all. The time signature is at bar 9
10. move it further to the left and observe that it has indeed left the BBT. The Bars:Beats ruler again shows the BBT marks
11. note that this effect cannot be obtained by dragging the time signature marker in one go from right to left. In that case the time signature marker will stay inside the BBT and jump wildly each time you cross the BBT marker

A crash can also be observed:

1. create new BBT marker with bars:beats 1:1, at bar 8 for example
2. create new time signature marker to the left of the BBT
3. watch it jump immediately to the right of the BBT ! That's already weird.
4. left drag the BBT marker to the right of the time signature marker
5. watch how a bunch of vertical guide lines disappear to the left of the BBT marker
6. scroll mouse wheel up
7. crash...
