The File->Recent Servers menus seems completely non-functional to me (v 6.12). The list of servers is fixed and unchanging and does not reflect any recent servers I've connected to. Also, the "Clear History" menu item does not clear this list as I would expect it to. How does this menu work? Is it broken?

Have you enabled the "Move to top of list on connect" option in Alt+O > Connect > Options ?

I see...yes this does make recent servers show up and clear history will clear the new ones that show up...but the "predefined" ones stick around... e.g. there are 12 entries to random networks I have never connected too, and they don't go away with "Clear History"... how do I get rid of them?
