bitmap tracer confusion for simple scan of words drawn by hand

[mintintegral18]

Thanks and thanks for the screen shot of settings and links to guides. I have yet to follow those. I've have tried 11 combinations and I'm not sure which parameter is creating these hair whisps lines. As a side issue, in case Xara is able to fix it, each time I zoom in to a layer and click the HIDE icon to toggle and compare each layer, to compare Layer1 bitmap tracer settings to layer2 bitmap tracer settings, the window focus area changes and I have to scroll the window to the letter I was using to test what changes occurred. Just seems like a bug or somehow hacked my zoom settings get changed. Ever seen this? If find the parameter combination to remove these high whisps, I think I'll work with that. I've tried toggling accuracy to high and low, keeping all other parameters the same, but does not change it.
