ProcessStartInf o duplicating code execution

[Matt]

I am running a exe from command line in my application and when I use
ProcessStartInf o it seems to duplicate all the commands within the function.

for instance I write a file. Without my ProcessStartInf o the file I write
does what it is supposed to do and writes 1 file.

With ProcessStartInf o it writes two files it even creates the random
ListName for the file twice (different numbers).

When I go look at it through the debug process and step into it, it doesnt
show the code being executed twice.

Any idea whats going on here? Driving me nuts.
Random R =new Random();
int MaxLimit = 5000000;
string ListName = R.Next(MaxLimit ).ToString();
StreamWriter sr = new StreamWriter("C :\\" + ListName + ".txt");
sr.Write(PointD ata);
sr.Close();
ProcessStartInf o psi = new ProcessStartInf o() ;
psi.FileName = "C:\\WINPOINT\\ import.exe";
psi.Arguments = "\"C:\\" + ListName + ".txt\"
\"P:\\PNTTEMPL\ \DATAIMP\\MMImp ort.imp\" \"P:\\2001\\bor rower\"";
psi.CreateNoWin dow = false ;
psi.UseShellExe cute = true;
psi.WorkingDire ctory = "C:\\WINPOI NT";
Process.Start( psi ) ;
psi = null;
