AV with Flash-ActiveX when closing App


in my App i have an own form with the Flash-OCX component. if i close this
form at runtime an free it completely, everything is fine, even if i close
the app afterwards. But, if i have the Flash-Window open and close the App
directly i get an ugly Access Violation at
BFF64E46 in User32.dll.  What's happening there?  Do i have to free
something before?
