A quick IE issue. Calling window.open with spaces in the window name will error is IE but works fine in Firefox
Example
window.open(‘myPage.html’, ‘My New Page’);
will error
window.open(‘myPage.html’, ‘MyNewPage’);
will not :)
UPDATE: Thanks to all those who posted additions here. By the looks IE complains about a lot more than simply a space in the name – special characters are not good apparantly and to be avoided to avoid possible problems.
