[Qt-interest] Webkit CPU usage under MSVC

Hello, I am using Visual Studio Express 2008 SP1 on WinXP SP3
and have successfully compiled qt-win-opensource-src-4.5.0 (LGPL)
from the VS command prompt.

I have a very simple QT application which uses Webkit, but I am
seeing 100% CPU usage on a single core machine, and excessive usage
on another dual core.

The CPU usage only seems to happen when showing html pages with
javascript in them (ie google.co.uk).

To eliminate my code, I also ran the demo browser application
in qt-win-opensource-src-4.5.0\demos\browser\release and navigated
to http://www.google.co.uk/ and saw the same high cpu usage.

Can anyone else reproduce this on Windows in a similar build?

Regards,
Richard.
