I suggest anyone who is interested in becoming a serious (note: not professional, although it still applies) designer/programmer to stick to standards and use browsers that render pages with said standards (such as Firefox or any Gecko-based, etc. browser).
IE accepts any incorrect things you feed it...
Trivial things such as:
IE: font-size: 10 pt;
FF/etc.: font-size: 10pt;
make it impossible to have a comfortable experience in sites designed for IE.
Note: IE also accepts the standard "font-size: 10pt;", so why they accept this space stuff, I think it's just to annoy designers...
Note: the code used is only for example. Almost all meassurement (sp?) codes have the same issue with IE.
W3Schools.com is a great site with lots of documentation on the correct use of languages and which browsers support what.
