Did you place, or copy/paste from Illustrator? Waht tool are you using to scale?
I tried copy and pasting and then I tried placing it. In the end I just pasted it and change the options in the past settings. Seems to have cleared up the issue. Do you know of a way to expand a image in Illustrator that contains embeded graphics?
It should be placed, not pasted, in my opininion. When you do that it is a single object and ought to scale without any issues at all.
Thing to look for when doing this is to make sure all stroke is set up outline. Also in indesign use the free transform tool.
Indesign does a lousy job of resizing stroked outline.
Placing the Illustrator file is a way easier option but again make sure you use the free transform tool
