The main window shows my original image, and the trace bitmap preview shows the background wash. When I apply the trace it displays exactly like the preview. I have some similar images where this hasn't happened, all generated from the same software in the same fashion. I've tried various settings in the tracce bitmap dialogue box, but nothing seems to help.
I would greatly appreciate if anyone could shed any light on this

Thanks,
