I'm sure it's dust, as I quit using K's Indicator Stop Bath when I went to pyro, and didn't resume when I came back to HC110. I just use filtered water.

I contact print and the dust specks are miniscule, but ALWAYS occur in the highlights and clouds. [hard and fast rule of photography]
I agree that fiddling with a negative is risky business, but bleaching a black speck is tough, and the scalpel trick is too mechanical and roughs up the surface of the print. I haven't tried the Sharpie, but my experience with Sharpies is that they aren't very sharp--compared with an 0000 sable brush, for instance. I have a 5X magnifier and can lay down a very small bit of pigment. I just need to know the best pigment to lay down.
Thanks to all who responded.
