Clarissa,

I'm not sure this will help in your case, but you might try the following:

SET LIBRARY TO FOXTOOLS

x=regfn("FindWindow","CC","I")
z=callfn(x,0, cWindowTitle)
y=regfn("PostMessage","IIIL","I")
=callfn(Y,z,274,61536,0)

If the application has a window with a unique caption, you can find that window by its caption (cWindowsTitle variable) and send a message to that window that it has to close.

HTH

Walter,
