We have an old project that is designed using VS2005 and WinForms. Everything works perfectly on Windows XP, but when I open the designer on Windows 7, everything breaks down.
The controls get sized to random size and some of them dissappear (or are moved to random coordinates).
What can we do to solve this issue? Should we switch to VS2008?
The problem was that we used TableLayoutPanel inside a GroupBox and not on the form. When we added the TableLayoutPanel on the form and moved the GroupBox into it, the designer stays ok.
