A program called WagerLogic and older versions of TortoiseCVS have been known to cause this problem. You can also try choosing a new download folder in your Firefox settings: ' Tools -> Options -> General (Main in Firefox 3.5) / Downloads -> Save files to -> Browse'.Ī Windows shell extension added by certain applications can cause Firefox to hang when choosing a folder location to save a file or when opening 'Options' or 'Downloads' from the Firefox (Tools) menu.
