>I have a really bad bug with the TabControl. I have one on my form which contains 8 tabs. They are TabPage1 to TabPage8. They appear in that order in the TabControl collection. I see them in that respecting order on my form at development time. When I compile, they show correctly. As soon as I run the application or if I quit the development mode and reload the VS.NET interface with that project, TagPage3 is moved to the end. Anyone would know what could cause this and how to fix it?

This is a known bug. See my article again. It shows how to remove and re-add tabpages at runtime.
