G'day,
I usually start MSIE 2 or 3 times at the beginning of a session. This is equivalent to opening a new window. Reading one thread while downloading another (or a page from another site) is a great productivity improver.

Another productivity improver is to click on File, then Save As File. This will allow you to save the page with a .htm extension, possibly on the desktop. You can then view this offline at a later date by double clicking on the file's icon.

Cheers,
Alan
