I have done this a couple of times (in an existing IDL session) but what I
see is that I can create the window, then put "another app" in front of it,
then select the IDLDE to type wshow, then wshow will bring that "other app"
to the front.
So here is the hypothesis. IDL uses the wshow command to switch the order
of the windows in the operating system alt-tab q. For instance, I have
IDLDE as the first app (current, on top, active) several other programs,
then the idl window0 at the 7th spot. I type wshow, and IDLDE becomes the
7th spot, everything else moves up 1 (idl window0 is then 6th). The most
recent "other app" was in the second spot, and it moves to the first spot
and appears on top.
So, in terms of the windows7 alt-tab queue, seems to me that the action of
wshow's error is that instead of moving window0 to 'zero', it is moving the
IDLDE
to the spot of the window0. Should be easy enough to fix.
cheers,
bob
PS, it's a bit different with another IDL window (i.e. the xcolors widget),
but I don't have the time to really look at that.
