The sun is boiling my head, warming my beer, and stopping me seeing the computer screen clearly.
I have work to do but don't want to shut myself away in a dark room.
Has anyone else had this problem on their computer? Is there a workaround for it or is it just one of those Microsoft bugs you have to live with?

Ouch, just burnt my finger on the mousepad thingy!

The easiest way to fix this well known bug is to move to the North of England. The lucky sods who live there never ever have this issue.
