CorelCad - Hatch Patterns not printing

I'm an experienced Acad user - my company is new to CorelCad.  Right now I can't print any hatch pattern with dots in it.  we've manipulated the .ctb files, point definitions, layer colors, line weights within layers, and all manner of other work-arounds.  the ONLY thing that's worked so far is to explode the hatch prior to printing which gives us a one-pixel dot (unable to make thicker with pens either from the program or in .ctb).... which is definitely NOT an answer.  Thoughts?

further diagnostics - i opened the file in acad and it printed perfectly.  opened it back up in corelcad - still the same issue - no dots.

thoughts?
