To reproduce in MEP 2013.
	Note the position of the orange timeline marker.
	Open Effects >Effect settings movies... (Ctrl + b) and click Cancel (Escape).
	Here the marker jumps to a the start of any (blue) range.
	It's mildly annoying because I frequently toggle the TV area display, and so that loses my place.
