I had an interesting bug submitted by a user, he wrote that our product was crashing in his Visual Studio 2010, which was a Traditional Chinese edition.
Typemock Isolator, being a Visual Studio add-in, adds a menu next to the Tools menu in Visual Studio. It does so by looking for an index of the Tools menu in the main menu bar, and simply adding the Typemock menu after it. However, the Tools menu is only called that in the English locale. In other languages, the menu might be called differently. In French, for instance, it’s called Outils.
