Nuno , everyone - not only you - supports the "old" Winbuilder, noone, not even you, develops it.
As said the "old one" works, and has been working for years.
Set aside the whiners and a few (highly debatable, and actually debated - to no effect) decisions/choices in the language syntax, Winbuilder (the old one) is a successful, good, working, software with an incredible amount of .script and projects for it, most of which perfectly working.
There is no real need to "develop" it, there are a zillion little, minor issues with it, all perfectly solvable, that for whatever reasons you and pscEx refused to:
Possibly under the effect of alcohol, drugs, senility or pride (or something else ) you decided to go for the current nonsensical "new" Winbuilder.
There is nothing "wrong" in the "old" one.
There is nothing "wrong" in the "new" one.
But they are different.
The first one is slower, has often a convoluted syntax (but that everyone has learned to live with and that is mostly documented) and a vast library of projects and scripts.
The second one is faster, has (most probably since we don't have access to it if not in some bits and pieces) a syntax that is as convoluted or more convoluted, has not any documented syntax and virtually no projects.
The first works (if the scope is to build whatever the user wants to build) the second also works (if the scope is to build only what you and Peter want the user to build).
I do understand how fun is to play with new things , but usually the fun is playing with new things together with all the other kids.
This is the spell that was broken , you seem to not being able to realize this, and I am only trying to tell you what you appear like not being able to see with your own eyes.
Of course both are your (and pscEx's) creatures and you are obviously very (if not welcome) allowed to ruin them, but - as a friend - I cannot but tell you what I see (which you are as well and obviously perfectly free to ignore)
