No, nothing will help. Having a DOS window flash
at you is a fact of life in the Windows world.
The START command (on WindowsNT at least) allows
you to spawn a process and return immediately to
the IDL command line, without waiting for the
process to exit.

I'm donating the award to Jim Hamell and his object
widgets page. :-)

nope: can't do either in windows. And having a shell in Unix is not too
bad for my
purposes -- it won't open a window but just log it's output on the
current terminal
window (using the command line version of IDL).
Thanks anyway,
Martin
