--- Comment #3 from Connor McAdams conmanx360@gmail.com --- Hm, so I don't seem to be able to reproduce the issue, but I can see a potential problem, which is that I'm not releasing the IRawElementProviderSimple returned from get_HostRawElementProvider in the last two calls to that method. I'll send a patch for this, and hopefully it helps.
Not sure why it doesn't seem to be reproducing consistently.
