Peter,
Thanks for the feedback. As a general rule of thumb, that advice works. I realize, however, that I've stumbled over the edge into BUGGY territory. After a lot of troubleshooting and my fortunate encounter with another posting (at the bottom of this entry) I figured out what is going on. Apparently VW-11 doesn't correctly class doors and windows made with earlier versions of the door and window tool. That is, doors and windows created with the new VW 11 PIO's class correctly. However, if one were to add Simple Door-2, Simple Window-2, French Door ... to the workspace and create an object, certain objects (namely trim and doors) won't class correctly. That is, they will maintain NONE attributes no matter what you do.
To the best of my memory, I happened upon this situation because I updated my file from an earlier version of VW. So, all of the window and door objects retained their settings from the obsolete tools. Is anyone else able to verify this?
p.s. Now that I'm using the new door tool - I notice that it includes a mandatory apron. Whereas, earlier versions of the tool required you to build one manually. Is it possible to turn the apron on and/or off??
