[issue] Events pushed into new lane by scrolling another

This was discovered in the same editing session that gave rise to this thread and so may be connected:

Rolling an event along a lane by scrolling its start point in the info bar causes any event in the way to be pushed down to a new lane. This can lead to a lot of new lanes all of a sudden.

This seems to be Front/Back related. If you move the event to Back before scrolling, it moves round the events. Try it - it’s an almost amusing diversion!

I’m being to get a picture, between this thread and the one linked to above, that the Front/Back feature is being used in lane editing in such a way that it’s producing some unfortunate side-effects.
