Unable to open room specification dialogue for foundation plan

[Keith_K]

For some reason I am unable to open the above. If I left click on the foundation plan nothing happens and when I right click I get the pop-up shown in the attached screenshot.

Only the foundation plan is affected. Things work as normal and the ground (1) and first (2) floors.

Any ideas why the foundation (0) plan might be different. I don't have this problem on any of my other plans.

Thanks

Could one of the walls gotten accidentally checked as "no room def"?

[Keith_K]

Thank you JoAnn. That did the trick. In fact every wall had been mysteriously checked.

[JoAnn]

You're welcome!

Well, I'll be damned! It's gone all funny again.

Time to delete the foundations and do them again even though none of the "no room def" boxes are checked. Hope springs eternal...
