Not a major problem really but recently when I've been trying to do this, I get the following error:
Your submission could not be processed because a security token was invalid.
If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error.
It happens both at work and at home, so it's not a browser or cookie issue I don't think. It might be my profile or it might be happening to others too, any ideas?
