--===============5781791347722213566== Content-Type: multipart/alternative; boundary=047d7b6d9fa29b8b8604e88d80d1 --047d7b6d9fa29b8b8604e88d80d1 Content-Type: text/plain; charset=UTF-8 It doesn't really matter whether you write to me or to the old mailing list, since we're probably the only people viewing that mailing list. I guess I muddied the waters by trying wxPython 2.9.5, which I think you had mentioned. Like 2.9.4, it does require a patch, with I've included in the VPython repository. See the updated INSTALL.txt file: https://github.com/BruceSherwood/vpython-wx/blob/master/INSTALL.txt I used 2.9.5 partly because it's now the version available at wxpython.org, and I wanted to make sure VPython works with it. On 64-bit Ubuntu 12.04 I didn't see your bug with 2.9.4 and I don't see it with 2.9.5. No one else has reported your bug (which doesn't prove that they wouldn't see the bug if they tried your example, of course). I don't know anything about gmane but would be happy to make the connection. How would I do that?
