I'm using Visual Studio 2008 and developing in .Net3.5.

When I create a new basic WinForms app and throw a couple of group boxes on and then run it I get a form displayed as it appeared in the form designer.

If I use controls from one of our libraries it displays correctly in the form designer with nice rounded corners on the group boxes but when I run the app the group boxes are displayed like an old windows 3.1 form. I've used GroupBoxes as an example but there are other components that aren't displayed correctly (tab controls, buttons...)

I'd like to post a before and after screen shot but I don't seem able to do this.

The library that holds my components and stock forms was originally written in .Net 1.1 but has been recompiled into .Net 3.5. Could this have caused the problem?

Just out of curiosity, what does your main method look like? Are you calling Application.EnableVisualStyles?

Thanks for such a quick response.

I hadn't got that in the main method. Now that I've added it it all looks nice.
