Unable to view the drop down bar for Dia\doc\api_reference\html

Hi,

I used to be able to view the documentation of Dia just like the 1st attachment. (source from: http://epydoc.sourceforge.net/api/epydoc.markup.pyval_repr-module.html) I would be able to search through libraries of codes, and find which module belongs to which library with the help of the drop down bar. The drop down bar really helps!!

Now whenever I click a module in the source code, it goes back to the top of the page everytime. It only happens since I’ve change my OS to win 7. Previously, running on vista, I had no problems with it.

Has anyone ever encountered the same thing and got the problem fixed?

For some reason, I’m unable to upload an attachment.
