Hi there I have the blinking alert 1.1.1 extension set up on my Mozilla Thunderbird 31 email and it worked great but recently it has stopped blinking when a new message is received. I receive the message alert box but it no longer blinks like it used to. I checked the settings options and the blink time is set at 2 sec as I have always had it set to but I get no blinking when a message is received. I uninstalled blinking alert and then installed it again but still no blinking. Any help sorting this issue out would be greatly received as I can't work out why it has suddenly stopped.

Regards Nigel
