When pasting text (a few hundred kB, e.g. 1000KB) into a text box, inside a web
page (it doesn't matter which, it could be the text box inside a Yahoo compose
message page, or in a Softpedia news page - the comment text box), the browser's
CPU usage goes to 100%.

The same thing is happens when opening an e-mail message inside a web based mail
client (e.g. Yahoo)... a big message (>400kB, like the ones that come from
rentacoder.com, containing new projects). To better observe this, you should
have a rather slow connection. Until the page containing the message message is
not fully downloaded, the browser's CPU usage doesn't drop below 100%.

In both cases, while the browser's CPU usage is high, all browser's windows stop
responding.

I'm using Mozilla 1.7.11 under Windows 2000 SP4 fully updated on
windowsupdate.microsoft.com
