Animation Tray stopped working

Hello,

I have Comodo version 3 and have Windows XP on my home pc. The green and red animation tray lights have stopped working on my Comodo icon at the bottom right of my screen.

I’ve restarted my pc several times but it makes no difference. The option for this is checked when i right click the icon so I’m not sure what else it could be.

Any help with this would be great.
Thanks.
