Comment 36 for bug 315996

I just downloaded Inkscape-0.47-3-win32.7z from sourceforge, uncompressed it, copied in a slightly modified launch_webbrowser.py, it has a couple more print statements. Same problems - no browser window and it is running python 2.5. The output is:
2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)]
after thread
