I've never seen a case where I was convinced that I was doing everything
right. (But it has happened; perhaps it wasn't just me...)

But of course I use Ada code to define controls. There is no C in Claw.
(Something about that statement looks funny! :-) Claw interfaces directly to
the Win32 interfaces.

The main reason that I and the other Claw developers go through so much pain
with Windows is so that the Ada programmer using Claw doesn't have to. As
much as possible, we "cover up" differences between Windows versions and
unusual behavior in Claw. (Which is why Claw doesn't support some of the
Windows-defined styles: experments suggest that they don't work, so we don't
include them in Claw.)

Although sometimes the options don't work anyway. And it is often the case
that some important details are missing in the description...

Could be. But that seems to prove the point: the world doesn't take
standards seriously. If they did, unclear and ambiguous standards wouldn't
last long. Another area for us Ada people to do some education. (See, I can
somehow relate this to Team-Ada. :-)
