What is the difference between DOA for D7

[Ashok]

compared to DOA for D6

I am getting AV caused by ntdll when I exit D7 after compiling a project with DOA components and running it then close it and exit.

D7 closes, after few seconds, the AV comes up and the memory address is not the same every time.

TIA
Ashok

Never mind.
This was not caused by DOA.
