@wkempf: That is what my brain says too.  I probably wouldn't even consider it if I didn't have so many years experience seeing how trend micro in particular, other anti-virus to a lesser extent, has caused ... well just wierdness.

We created a separate app that calls the same API using the same P/Invoke and logged the results and had the user randomly run it whenever they felt like it.  It never failed.

I'm perplexed.
