<p>There haven't been any official tests done, mainly due to there not being many Windows developers, and even fewer with Office installed, and as one of the very few, I don't want to upgrade Office yet... Also there are a few quirks in v2 with PPT 2003/2007 so it's possible your hitting the same problems with 2010.</p>
<p>I was hoping that since every version of the PPT API has been pretty much backwards compatible with the previous version, that this trend would continue...</p>
