WaitWindowOpen anomaly I'm encountering

[JRS]

Hello All,

I looked around to see if my issue has discussed before
and didn't find any references. If it is a duplicate I'm
sorry.

I'm using Macro Scheduler Ver. 9.0.049e - January 2007

I never have any problem(s) with WaitWindowOpen on
a window name:

Example:

Let>WIN_USEHANDLE=0
WaitWindowOpen>Microsoft Excel*

However, when I use a window handle:

Let>WIN_USEHANDLE=1
WaitWindowOpen>WinHand1

no problem changing window focus back and forth to the
given window but the robot hangs when I attempt to
do the WaitWindowOpen ...

Is this the way it should be, have I missed something?
etc. Once again my apologies if this has been discussed
before.

Window handles are assigned when the window is created. They therefore change from one session to the next. And if the window is created just before it is shown, then destroyed when it is closed then the handle will be different every time the window is opened. Therefore in most cases WaitWindowOpen with a handle will wait forever, since there is no way of knowing what the handle will be. You can't hard code a handle into the script as it cannot be determined. It is assigned by Windows when the window is created.
