Great thought. I just tried it and it still has the problem, though the temp files are created in the new spot. The scenario that produces it seems to have the following:

1) compiled as a MTDLL
2) run in-process by an app that changes the default folder
3) DLL is not in the same folder as the app running it.
4) something about the phase of the moon and the latest score of the NY Yankees

The DLL does however know where it started up, where to find the data, etc...
