Оконные сообщения X Windows

[pavelp]

Здравствуйте!
В моей программе необходимо реагировать определенным образом на создание окон, изменение их размеров, перемещении и т. д. Для этого я получаю сообщения от рутового окна с маской SubstructureNotifyMask. Но вся беда в том, что, например, при создании окна (я запускаю какое-либо приложение) начинают приходить не только сообщения CreateNotify, ConfigureNotify и MapNotify. А так же приходят сообщения и DestroyNotify. Получается, что создается не только одно окно, а несколько, а некоторые из них сразу же после создания уничтожаются. Такое же происходит и при попытке реагировать на другие действия с окнами.
Подскажите пожалуйста:
1. Есть ли другой способ реагировать на описанные действия с конами?
2. Почему приходят сообщения о создании еще каких-то окон и об уничтожении каких-то окон?
Привожу небольшой лог (запускал клнсоль из KDE):
