Blockview has problems with Solid-hatches

Hi,

I made traffic signs to be used as "Blocks". Every sign is a single DWG, every sign consists of solid-hatches and a surrounding polyline. Also I made a modeless dialogue with "DWG-list" and "Blockview" to manage it.

This is what I have and got:

• Original drawing:
  


• Shown in DWG-list:
  


• Shown in Blocklist when inserted:


• Blocklist after "pan: "

Any way to get a better result in Blockview?
