Mouse freezes

I have a new Inspiron 530 with Vista Home Premium.  I have been having problems with my Logitech wireless optical mouse (its a couple of years old).  It has been freezing up occasionally.  It always seems to happen when the computer has gone into hibernation/sleep, but doesn't happen every time.  Sometimes I can reset it and get it to reconnect, but most of the time I need to reboot.  Once rebooting didn't work initially and I also had to reset it.  It's using a generic driver as their isn't a specific Vista driver available for it.

 

Any recommendations on how to problem solve this?
