So in short, it would appear to me that it is not working as a multi threaded dll :(

VFP will steal 100% of the CPU while processing (esp. queries). Maybe that's what's happening?

Sorry, no. The primary thing I had used this for was a nice animated GIF and progress bar - I hated how the animation would freeze when my main VFP app. was processing. It kind of defeated the purpose of the animation. Flagging the form as OLEPUBLIC and instanciating it that way got rid of the freezing. I wasn't using any third party library for this.

Is the code you're calling via the DLL just code that does processing (no UI)?
