Bitmap resolution profilelab v 9.1

[JimBrown]

I'm trying to mask a bitmap (Trace the outside around it). When I select the bitmap it is hi-res but when i try to trace in vector mode, the bitmap graphic becomes low res on the edges are big pixels. It'a a new laptop I'm using and i don't remember it being that way on the previous computer. I've been using signlab for 20 years or so ,started with v3. Thanks for suggestions.
