Wall Hatch Gone!!

[howard.16379]

I have a dwg file (more than one actually) that sometimes shows the wall hatch, and I open the dwg again and the wall hatch is not displayed. The Wall Style has it correctly; Hatch is ON; the layer is ON; RegAll doesn't help; it just sometimes doesn't show up?!?! Any suggestions??
Thanks
Howard

Here are a few things to check on:

your MAXHATCH environment variable

If the hatch displays sometimes and not others, it's probably not the MAXHATCH variable. You might just need to use the OBJRELUPDATE command to refresh the object display. (Since this command is a lot to type for those of us that are keyboard ccchallenged, we've put it into our ACAD.pgp file.)
