Sorry for late reply here as well Vincent - 

I use the TAsyncProc in both applications (each is actually a full GUI app, 
not cmd line). It would seem that any app I create that calls the wvdial 
script using TAsync (or TProcess) can not 'see' the internet connection, but 
all 'external' apps (browsers etc) including my own Laz apps can.
