Re: A question to the APL vendors on Windows GUIs ...

Since

1. there are more Windows developers than Linux or Mac developers
taken together
2. there is no organisation (in the world) using Linux or Macs who do
not ALSO use Windows

I'd say that it is Windows that defines the standard; this is far from
being "stuck with the "old"
Windows" ... it is abiding by the most ubiquitous standard.

You said: "I also did a lot of exploratory work on internet
interfacing (Browser DOM models etc. etc. ) as well as reporting loads
of bugs ( 100's of Emails ) in the latest verions of my APL
interpreter." ... note "my APL interpreter". So your question was
hardly general. PS. I have used web forms & DOM from APL without any
problems.
