Bluetooth Mouse no longer working after this afternoon update

Once again the Vista updates bite my systems in the preverbial behind - with
each new update I never know what is going to stop working next. Now it is
my bluetooth mouse that will not work since the system rebooted after
installing an automatic update. The system says that it is connected but in
fact it is not. Vista is becoming ever more tring of my patience - before
Vista I use to be calm. Now I am so angry with Vista and Microsoft I feel
like blowing them up!!!!!!!
