CreateProcess and StartupInfo

Hi,
I am trying to write a Delphi5 app that will call the default browser into a specific size and location. I cannot seen to get this to work. Here is the code that I have for the CreateProcess and StartupInfo:

procedure TForm1.ExecNewProcess(ProgramName : String);
var
StartInfo : TStartupInfo;
ProcInfo : TProcessInformation;
CreateOK : Boolean;
begin
FillChar(StartInfo,SizeOf(TStartupInfo),#0);
FillChar(ProcInfo,SizeOf(TProcessInformation),#0);
StartInfo.cb := SizeOf(TStartupInfo);
StartInfo.lpDesktop := nil;
StartInfo.lpReserved2 := nil;
StartInfo.dwFlags := STARTF_USEPOSITION or STARTF_USESIZE;
StartInfo.dwX := 0;
StartInfo.dwY := 0;
StartInfo.dwXSize := 100;
StartInfo.dwYSize := 100;
// StartInfo.wShowWindow := SW_SHOWNORMAL;


CreateOK := CreateProcess(nil, PChar(ProgramName), nil, nil,False,
CREATE_NEW_PROCESS_GROUP+NORMAL_PRIORITY_CLASS,
nil, nil, StartInfo, ProcInfo);

{ check to see if successful }
if CreateOK then
//may or may not be needed. Usually wait for child processes
WaitForSingleObject(ProcInfo.hProcess, INFINITE);
end;

Any ideas why the browser (and I tried opening notepad and other apps and still cannot get this to work) still opens up in the size and location it wants to and not in the specified size and location?

Any help would be apperciated, thanks
