Symptoms

A program window may not be visible if the program stops responding (hangs). A program is considered to be hung if the program does not respond to window messages within several seconds, and a status of "Not Responding" appears in Windows Task Manager. In the problem state, the Win32 IsWindowVisible function does not return the WS_VISIBLE flag.

A Microsoft Visual Basic program may report the following error when the program tries to use the SetFocus method on a window:
Run-time error '5': Invalid procedure call or argument.

Cause

The Ghost Window feature creates ghost windows on behalf of a program when the program does not respond correctly to window messages within several seconds and is considered to be hung. The original program window's visibility state may not be restored before the program starts processing.

To create a custom Application Compatibility database:

  2. Right-click Custom Database, and then click New.
  3. Right-click the new database, and then click Rename.
  4. Type noghost as the name of the database.

More information

The following information about the GetMessage function is documented for the Ghost Window feature in Windows XP. For more information, visit the following Microsoft Web site:
GetMessage function

If a top-level window stops responding to messages for more than several seconds, the system considers the window to be hung and replaces it with a ghost window that has the same z-order, location, size, and visual attributes. This allows the user to move it, resize it, or even close the application. However, these are the only actions available because the application is actually hung. When in the debugger mode, the system does not generate a ghost window.
