Yes, that's the good point, it mainly works now.
BUT: DON'T FORGET - I DID say, they're experimental yet! Didn't I?

Yes, there are a couple of problems with this beast. I _suppose_ it's
mainly caused by the need for using this weird controller thing, that just
serves to introduce another layer of complexity and seals off the final user
interface from the calling program. As I wrote in my parallel message (you
might not have read it when you wrote the above mentioned), there IS a
deep-lying, well, "effect" causing parent forms to be affected adversely,
mainly when closing such a dialog. Debugging these things seems close to
impossible, because the pertaining functions are used for most every action
dealing with program execution, so breakpoints are impossible to use, and
following the flow of execution wildly jumps through most of the kernel
(gui) code. It might be just a little quirk in the focus handling I found;
on Linux, Martin opted to always return the focus "to parent", even when
there isn't even a parent window. I _suspect_ that this could be coupled to
the "blinking" effect, which occurs because all the application windows
seem to be destroyed and rebuilt again when a "newdialog" terminates.
(But X11 error handling is implemented in a rather, err, overly optimistic
manner, i.e., when an error has been found and been "resolved", the
affected functions still return an "ok" result anyway.)
BUT a question here - and this is a VERY important one: Does this blinking
(and possibly all the other adverse effects too) also occur under Windows?
If it didn't occur under Windows, I might be on the right track with the
above assumptions, otherwise, the problem might even be rooted deeper still.

Yes, I did that, and I found weird behaviour myself. That's why I wrote my
last message, and that's a complete no-go for freely published code.
Experimental is in order, maybe there's someone who can find the cause of
the problem quickly, faster than I can. But it HAS definitly to be made
clear that there IS A PROBLEM (and probabely a couple more).
> Maybe you could take a look?
I'm about it (besides some other tasks, of course), but I'm not really
optimistic to have a solution fast.
BTW, the other modifications should be unaffected, i.e. the db units and
the stat file extensions, which are just minor patches anyway.
