Can you tell me to which adress the stack is be set on starting a new app ?

This does make no difference.

By the way: How does the process loader calculate the reserved stack size for
the newly started app. Does he takes on of the entry in the executable or dll
below ?

SizeOfStackReserve      00200000 (a)
SizeOfStackCommit       00001000
SizeOfHeapReserve       00100000 b)
SizeOfHeapCommit        00001000

(I have changed the value (as) and (b) but the taskmanager tells no difference.)
