RPCSS dos window wont go away after loading Delphi 4 CS

I installed Delphi 4 client server on my machine. All works but
since then every time it starts up I'm left with a dos window 'RPCSS'
that doesnt close (Yes I've changed the close on exit property just in
I havent a clue what or where this window comes from. I have to manually
close it. (PAIN)
Tried uninstalling & Re-installing without success
Even upgraded to WIN98(Fingers very crossed) and still the ruddy thing
wont go away.
Near resorting to wiping the hard disk.
Any ideas please.
