More differences between Internet Explorer and the other browsers

Directly from mir.aculo.us. Internet Explorer does not like certain names for the id of your controls.

People using "tags" as id are having problems to print the page (?). Explorer also gets confused if you use "options" as id, but this time you will probably get a javascript error. To make good things better, it also has problems if you use as id the name of another control.

Another example of problem that will not be discovered with any w3c test.

Test early, test often, and with as much browsers as possible!
