Now i know, what you mean with run! Now i'm satisfied, but ...

... i have to prove you wrong!

javaw.exe (from sun's java-jre) is a window-mode application, right?

So how can you explain, that i see text within cygwin, when i run javaw.exe?

$ javaw
Usage: javaw [-options] class [args...]
           (to execute a class)
   or  javaw [-options] -jar jarfile [args...]
           (to execute a jar file)

where options include:
    -client       to select the "client" VM
    -server       to select the "server" VM
    -hotspot      is a synonym for the "client" VM  [deprecated]
                  The default VM is client.

See?

It seems to be the standard-behaviour of the windows shell (cmd.exe) to
detach the application from the console if it's starting a window-mode
application. But cygwin doesn't detach the application.

So of course, you're right if you say:
if rxvt would be a window-mode application, then you wouldn't see
anything if you execute "rxvt.exe --help" from the windows-shell - but i
ask myself, if this is necessary.
