You need to use CLEAR ALL to release the fxp. This is documented in article Q192960, which also states that "This behavior is by design".

>The only way is, if you ran demo.exe from the command window, then issue clear all, otherwise finish it. But for this type of programs, that will hopefully run in lots of applications/machines is not something allways posible to do.
