Looking for tips about Storyline 2 motion paths

I just got upgraded to Storyline 2 and I'm busily testing out different options. I'm liking a lot of the results, but I'm having issues with straight line motion paths when I try to extend them.

For instance, I have one animated narrator that moves from bottom left to bottom right of the frame, but every time I try to lengthen the motion path, it's not perfectly straight and the image appears to drift up or down a bit when I preview. Gridlines and guides have helped somewhat, but it is there another tool or tip I can use for better results?
