Ever had this happen to you while you were trying to debug? You're trying to debug your Javascript code, and then you accidentally set yourself up with an infinite alert loop, and ....
, but be prepared to hit Ctrl-Alt-Del, choose Task Manager, and kill your browser.
*sigh* The browser vendors really need to find another way to make these alerts show up, such that you can cancel script.
Update: Oooh, nice, Chrome gave us a good one ..
Sadly, checking it also causes this blog page to not refresh, the whole browser becomes unstable. Click on the <-- (Back) button to make it behave normal again.
Opera plays nice too.
Internet Explorer, Firefox, and Safari all FAIL.
