#2713 iconified toplevel cannot be restored (Windows only)

[Uwe Traum]

The attached example causes the following problem:

1. Start: wish desktop.tcl
2. Press Button "Dialog" -> Application modal toplevel appears
3. Iconify all existing windows using the "Show Desktop"-Button right next to the Start-Button of the Taskbar
4. Start another Application (eg. firefox)
5. Try to restore the iconified TK-App using its icon in the taskbar -> nothing happens !!!!

Workaround:
The only way to restore the dialog is to push it to the foreground with the Windows Task Manager.
But this can mean that it is shown everytime another application is started.

Comment:
The problems only occurs if the dialog is application-modal. The grab command
seems to cause the problem.The example has been taken
from the Iwidgets Shell Widget class and has beem changed so that it runs without
Itk, Itcl and Iwidgets. The implementation is very similar to the TCL script
implementation of the tk_messageBox dialog for Unix.
