I have a search form that isn't a MDI child, and I'd like it to float over the MDI.

I saw a piece of code for it long time ago which I'm not able to find again... although when I tried it long time ago it always made my program to crash.

I thought of making the form to stay always on top, but then if I set the MDI always on top the search form won't, and if I swap their priorities the MDI won't either.

Does anyone know how to solve this? Thanks in advance.
