>Hi!
>I am using a loop with GetWindow and GW_HWNDNEXT, but the window I am looking for does not come up in the list. It is visible and I can see a title bar, but it doesn't get recognized by the GetWindow loop. What else could I do to find it? I need to wait until it is done with what it is doing before I can continue in my program.

Try retrieving the desktop window handle and use it as the first call, to retrieve the first child window at the top of the Z-Order.

DECLARE INTEGER GetDesktopWindow IN Win32API
DECLARE INTEGER GetWindow IN Win32API;
  INTEGER hwnd, INTEGER dflag
lnhwnd = GetDesktopWindow()
lnchild = GetWindow(lnhwnd, GW_CHILD) && GW_CHILD = 5

The proceed from there using GW_HWNDNEXT.
