[Java-gnome-developer] Attachement problem with the wiki

[Abcdefg <ab...@so...>]

Hi I have a problem with the wiki. I don't know how to upload a file
I went to this page:
http://java-gnome.sourceforge.net/cgi-bin/bin/view/Main/GladeWidgetPropertiesAndEvents
and than clicked upload attachement this is where I'm than but I do not know
what to click then..

Is this a bug or am I doing something wrong?

Thanks,
David
