Re: Multiple Monitors on Windows

There was a thread with the title: "Open interface on second screen" 
a few months back (dated 7/29/2004, and so it seems to deal with
4.3, not 4.4...) that talked about this issue. Relevant excerpts would
be:

   "Our customers are complaining that with our new LWW 4.3-based beta,
   windows that should open on a second screen get cluttered on their
   main screen, making our stock trading tool almost useless (these
   traders often use even more than 4 displays!)."

   "The CAPI currently doesn't do multi-screen display."

Now, this was several months ago, and in a older version than the current
4.4, so it might not be the case. Nonetheless, it might help to take a look
at that thread. Google doesn't seem to have records of this list though, so
if you'd like, I could send you the nine messages composing the thread; just
ask.
