Error: KeyRocket menus and popups are invisible / behind the main window (Windows XP)

On some computers running Windows XP, all the menus and popups from KeyRocket seem to be invisible because they appear behind the KeyRocket main window. This is caused by a bug in the Windows XP display system. Microsoft released a Windows XP hotfix that addresses this problem. After installing it, the menus and popups in KeyRocket are displayed normally.
