I noticed it does leak only on certain conditions: I tried to create another dummy WebBrowserComponent and deleted it immediately after, and that did not cause any additional leaks, so I wonder if it’s only the first instance causing it, or maybe the fact that the dummy one I created was neither added to another component nor set visible to the user…
Has this been fixed in the tip yet? I’m seeing the same thing in 1.50. FWIW, one of the three leaked objects appears to be the IOleClientSite implementation.
