Andrew,

>No I haven't tried sys(2333) - I'll give it a shot, but I can't see why that would make a difference, there's not an ActiveX control being instantiated within VFP - it's a COM server.

I know, thats why it is a shot in the dark.

>I could be displaying my lack of complete understanding of things COM, but I thought these were two different things, or at least that one was a subset of the other.

To be honest I don't know if they are related or not, I think it's worth a try.

>I'm also not sure where I'd switch it on/off in the code. Because it's event driven and I don't even seem to get to the start of the event code, there doesn't seem to be an appropriate place to put the sys() call.

How about before you instantiate the com-server ?
