ADT 2009 Wall dropping veneer

[jopoco2005]

I am using ADT 2009 in Windows 7 64 bit. When I draw an exterior wall, (Stud rigid 1.5-brick 4), the veneer shows on the floor plan view, however when i go to elevations/iso, it drops the veneer. Prior to adding windows/doors it was fine. After adding windows/doors, this occured. I have gone in and removed the walls and added windows doors back again, the problem returns. I have gone through and compared properties on walls this happens on and walls that worked fine and can find no difference. Does anyone have any suggestions?

Is there a cleanup error on the problem Wall?  In particular, since the issue only shows when you add Doors and Windows, are you placing Doors and/or Windows so close to the Wall end(s) or intersecting Walls that there is insufficient room for the Wall Endcaps or Wall Opening Endcaps to be resolved?

Ther are no exclamation marks or errors that I see. I am well away from corners and windows are spaced with more than 1' between them. I am new to using the 3d portion of desktop. I tried to attach file but it is too large.
