>Hi,
>I have just got hold of Visual Studio 6 and recompiled a couple of my DLL's then moved over to the IIS4 web server - after regsvr32 /u them, recreating a new VFP6 setup etc. One of the problems of VFP5 was the lack of multi-threading, does VFP 6 support this by default or do I have to change something in VFP6 or IIS/MTS ?

It's a problem. VFP 6 has a threading problem, and multiple instances of an object can (and do) tromp on each others' data sessions. Several people have reported that this will be fixed in an upcoming Service Pack.
