iGoogle Bug?
A simple way to make your iGoogle page blocked
1. Login to iGoogle, and select any gadget's option menu: Share this gadget.
2. Before the next page loading completely, press "Cancel" quickly.
3.Now, the darken screen remains on screen and nothing you can do. (OK. you still can reload this page)
4. If you do not do this under a max screen size window, you can resize the screen, and a interesting screen shows up. you can still click anything outside the darken screen.
m...... This bug happens just because we do not let Google to load the page done. But Google still can prevent this happens. :p
