indefinate waiting time when loading maps

[Noggin on Wheels]

i find that upon joining a server everything loads up correctly and smoothly the map strategy is shown for a minuite or 2 then i get the team menu screen, but when the server changes level i am left with the map strategy screen and then nothing it merely sits there idle. this only happens when the server changes level and due to this I can only play one match on one level then I have to restart Fortress Forever as there is no way of returning to the main menu. when i have pulled up the application list (Ctrl+Alt+Del) it registers the program as running perfectly, can someone please explain why? also might i add that a button/hot key should be added to the loading screen so that in the case of such evnts players are able to opt out and go back to the main menu.
