It's a bug that happens with all browsers. It happens sometimes but I've been working on reproducing it without success. I used to use Firefox and then I switched to Chrome. Firefox is getting bloated and is slow and clunky compared to Chrome.
Haha, I just opened that thinking hmmm.. What have I done wrong ahah. Thanks for pointing that out eker676. I was really trying to see what I thought I had done wrong heh.
