This happens always with one of my project that has bunch of controls (more than 30 ) . The controls don't move but the IDE halts for about 5 to 10 seconds then resume again . The Tab problem , is annoying like hell . Sometimes , tabpage1 is indexed as 3 or 4 . I'm using VS.NET 2003 Arch. Enterprise (C# IDE) . I've not heard of any fix for this problem .
It looks to me a damn bug .
