Can't get shapes to line up
I've noticed this problem a few times so I thought I'd ask if there is a solution. When trying to line up shapes, often one edge will not visibly line up even though the wireframe points are exactly the same and the guidelines when resizing the objects seem to snap to the right position.
Here is my current example: http://imgur.com/toAQSR4
I am trying to build a long colored bar that I will fill with buttons, and at the top I want a folder-tab looking piece to put the title on. However, as you can see the right hand edge will never line up. It's like Articulate thinks they are in line but it does not draw the shape properly. This carries over into the preview mode as well. It's the same problem with outlines turned on or off.
Any thoughts on how to make this work?
