I have used Win XP, IBO4 and Delphi 7 with IDE using XP manifest.

I noted the labels: Alignment, CharCase, ... on Field Properties,
disappear(not visibles) when using property editor of query(right click on
tib_query and/or tiboquery, and next, edit option).

Searching on source code, I found IBF_Quey form.

I noted, then, if I change the ParentBackGround property of gbReadOnly to
False, these labels become visibles. This property is not related directly
to labels disappearing, but when False solve the problem.

Only a note when Jason make IBO completely compatible with Win XP.
