Just read this post:

and the other postst in that thread.
And I'd like to receive an answer at my question in that post who's coding and compiling the final versions of those updates. I doubt seriously if it's jv16 himself. If not, the new developer(s) are making a mess of the program that used to be so simple, good and fast.
