Whoops, right. So the problem would be that in IE only, .fadeTo ("slow", 1) makes the element completely visible and then pops to 50% opacity based on the stylesheet when the element's filter property is removed. > There is no way to fix anti-aliasing if the user *chooses* to use > opacity since this is a browser issue, If the user chooses to set a 50% opacity in the stylesheet that should work properly in IE as well, right? A fix for antialiasing shouldn't break something that currently works properly across browsers. > Calling it an IE-bug doesn't make it go away. This is a cross > browser issue, pure and simple. If this problem has a good fix, it should be fixed. There are several cases that will break differently in IE when this proposed fix is applied. It's not achieving consistent cross-browser behavior. There may be a solution out there still, and if someone has one they should post it.
