It does. Almost always. It's the seldom cases when this does not really work which annoy me that much.

well, it is almost exactly the case: WinNT 2K. And I cannot change this.

I am NOT reporting a problem. Everyone knows there are these problems, it's just almost no one (including me) cares enough about getting anything to work sanely on windows.

Please, stop assuming that every my complaint is a bug report about cygwin. It is not. You can use my mails as you please, even as bug reports. If you ask nicely, I can provide more details maybe. But I am not asking YOU for anything, and not complaining to YOU about anything.

I _do_not_ like how Cygwin workarounds windows, but I respect the effort and understand why it happens. Still, I'd prefer it die. I'll try to keep it moving, but no farther than needed and only when I really have to.

In windows you have to do hell of a lot useless typing to write what you consider a "well-written program".

That's right. They are not _ported_. I'm not interested in xterm which prints page in a minute.

Whatever you say. I never expected them to, personally.

Maybe. I wouldn't blame that poor windows programmer though: it's hard, boring and in 99.9999% of starts of that program - dead code.

gui applications detach from cmd (not from cygwin console), so that kind of pointless exercise.

I'd suggest calling cygwin ports unsupported.
