Alakazaan's Disappearing Square

Hello, I am Alakazaan. Let's play a game. The rules are simple: if you can click on the purple square in the middle of the page, you win. However, if the square was to, I don't know, disappear, that would be your problem. Ha ha. Have fun figuring it out...!
Oh, and according to knowledge I have acquired... it is best if one uses Firefox or Internet Explorer, or the trick may not work...
