it seems that the second program doesn't get a chance to initialize its
ddeml
facilities before the first tries to connect, hence the trouble
can you provide more information on the start sequence ? sounds like a
Wine bug
in 16 bit program startup & synchro (or some undocumented features in 16
bit 
Windows code)

on PDV side between the spawn of DISP and the connection trial
on DISP side between the program start and its DDEML initialization

A+
