Hi Christoph,

please make sure to honor the SystemWindow reuseWindows preference when
> revising this behavior. :-)

I also noticed what appeared to be a slight regression with this when the
MessageTrace was spawned by the (I)nheritance function, and then again from
the same method in the just-spawned MessageTrace.  It spawns another,
duplicate, MessageTrace.  After that, however, no more are spawned by doing
the same behavior.  Very strange!

I traced the cause to this line of code (see attached fileout).  Marcel
made this logic change when he also introduced the "context" and
"requestor" complexities into the method.  The compact comment there says,
"Search for the requesting window to ignore it later.".

After fixing the squeak source server, revisions is working again and I
found the good comment Marcel made about the change (even though I disagree
with it).

Avoid reusing a window if it is the requesting window. This is useful for
the "browse" button in the system browser or even for the "hierarchy"
button in the hierarchy browser if the hierarchy is the same. A common yet
simple way to duplicate a window without using a halo. Since this is an
explicit user interaction, it is not expected to interfere with the "re-use
windows" preference. I suppose. :-)

So, I actually rely on Reuse Windows to *top* the requestor window (I
always use the, "Windows' Contents Are Always Active" mode) if it's the
only one, because the point of Reuse Windows is to not have to _know_
whether that's the only one open, and therefore avoiding opening a
duplicate.  Avoiding unwanted duplicates is actually the purpose of Reuse
Windows.  And if the users' goal is explicitly to make a duplicate, then
don't understand why the duplicate halo, even despite being at another
user-interface level, should be an issue.  What's wrong with using Squeak's
power?  And even still another way is to simply make it dirty on purpose.
So, I'm not a big fan of this change.

Best,
  Chris
