Windows not showing

[Al Launier]

I have CA 9.54. For some reason the window in the outside wall of each of three gable dormers are not showing in a cross section view, or the full overview. Only the window casings are showing in these two views. I can select them in either the cross section or full overview. However, they do show clearly in the plan view and the floor overview. Don't know how to take & post a picture here, otherwise I would (tips on how to do this would help also).

I have deleted the exterior wall, rebuilt it, added windows again, but to no avail. Any suggestions??

Thanks,
Al
