Ronald, 1) I appreciate the response. 2) Can you check one more thing. I'm sorry, perhaps I didn't go into enough detail, but if you create one fill object to C:B.P.B4 (or whatever) and another to C:B.P.B3 they will both fill and unfill together. Anytime any bit is set (the pakcin is non-zero) all the fill items (or visibility, or any discrete operation) will exhibit the TRUE condition. At least that's what we are seeing. So it looks to us like Foxdraw is performing the action on the PAKCIN as a whole, and not on an individual bit. Let me know.
