Drupal 7 CSS3PIE module not working on IE8
I have installed the CSS3PIE module to Drupal 7 without error. As far as I can tell all is in the right place. However, no theme works on IE8. I am using the Bartick theme for now and have made the recommended patches and mods to colors.css and others found on help and support forums of the Drupal web site.
Still PIE is not changing the theme in any way that I can perceive. Yes the library has been located in sites/all/libraries/PIE and that URL is in the CSS.
So where do I go from here?
P.S. Given the moves by Microsoft on IE9 I would think this would become part of the Drupal Core. Just my opinion.
UPDATE - after considerable playing around I was able to get something to appear to work but I don't know what it is. See the attached screenshot. The tab at the top should not be there and I cannot find what it is or what it is supposed to do. It does have the rounded corners but no text. It also does not have an action when clicked on. ? ? ?
