A free tip as a result of a half hour of frustration. If anyone has any further insight about exactly what's going on and why, I'd be interested. <tip type="IE/Win, onclick, and encoded characters in the URL"> Internet Explorer interprets encoded characters in a URL passed to an onclick event using "this.href", causing the link not to work. For example: <a href="http://www.omb.gov.on.ca/e%2Ddecisions/pl030623%5F%231361.pdf" onclick="window.open(this.href); return false"> does not work in Internet Explorer 6 for Windows. However: <a href="http://www.omb.gov.on.ca/e%2Ddecisions/pl030623%5F%231361.pdf" onclick="window.open('http://www.omb.gov.on.ca/e%2Ddecisions/pl030623%5F%231361.pdf'); return false"> does work. Both links work in Mozilla-based browsers. </tip> Cheers, Noah
