I think what you have seen is typical for the kind of problem I have described, so I think we are looking at the same thing here. We know this does not happen on Linux with 3.3.6 but it does happen with 3.3.5 on Windows. We can't test 3.3.6 on Windows, so the only combination to test would be 3.3.6 (your version) on Windows if you have access to it. If not I will probably go ahead and purchase the commercial version from Trolltech. I currently have the commercial PyQt version which comes with a precompiled version of Qt 3.3.1.
