Dear Peechee,
Funnily enough, I would love that feature, I have been reduced to writing a script to set the alarm.
I have absolutely no idea why this should be so, I imagine it is a registry entry that has become corrupted.
I don't suggest a re-install, but are you competent when it comes to registry hacking?
If you could export that branch of the registry we could examine it as a text file and then create a registry switch to turn it off and on!
If anyone else has ideas please feel free to suggest them.
Regards Jim
