I did that, and found only your post.

So it does, sorry about that, try "ShellAndWait"

I would have thought that "Shell" applied to executing an external process
rather than to a call to a DLL routine. Am I wrong?

Yes you are right and perhaps I misunderstood your situation. Reading your
OP again I don't understand why there is such a problem calling your dll.
Normally when VBA (or an Excel formula) calls a function, even an external
function in a dll, code waits until the function returns its result.
