Using NUnit 2.2 I get this error message:
System.ApplicationException: Unable to load <MyFile> because it is not located under the AppBase.
However, I can open an assembly (File | Open) and run the test but if I save the project, quit NUnit, reopen it (either by the icon in my start menu or by a double click on the *.nunit file) I can't get it to work anymore. Anyone got a clue?
(I use .NET 2.0 Beta, if that's important)
