Sigh.. Try to use the SEARCH function in the top-right corner since there are threads catered to problems with YM 3.0 already.. As with your problem, I don't have that problem which could indicate that the problem might be on your internet connection, other apps are interfering with YM, or something's wrong with the setting/preferences with your YM. Try to uninstall it completely (including preference files) then download again the installer from another source. Install it and see what happens. Check your internet connection 'cause it might be fluctuating. YM seems very sensitive to that even just to very short interference. Check your network settings and firewall settings if they don't interfere with YM. If everything fails, pray.
