Weird compression when importing jpgs?

Hi all,

Fairly new to Flash but I was wondering something. When I look at a jpg in Photoshop, the quality is fantastic and the white border is sharp.

When I import that same jpg into flash and convert it to a button, it somehow looks a tad odd around the edges, like it’s been scaled by 0.1% or something, enough to make the once crisp white edge, look anti-aliased.

Has anyone experienced this before? Here I’ll show zoomed in versions of what I mean. Is there any way to fix this?
