I just purchased SIG Pro (v2.5.7), having used the free version several times. In IE9, the SIG Pro gives a really nasty result. All other layouts and themes seem to work fine. You can see what I mean by the image I attached.

In FF and Chrome it looks great, but not IE. Besides the messed up look, the images load SUPER slow in IE9 for some reason. My template is made with the newest version of Artisteer, and I’m using Joomla 2.5.1 Stable.
I would appreciate any assistance with this issue, or a point in the right direction.

** Edit: Here's a thread from from 6 months ago with the same problem .. 6 months, any information on this?

This is from SIG PRO documentation:
Update on October 2011: It is important to understand that the "Polaroids" gallery layout makes extensive use of CSS3 which is not fully supported by all versions of Internet Explorer (IE). In order to make IE6 to IE8 compatible with this gallery we use additional JavaScript code which "triggers" behaviour in those browsers similar to CSS3's capabilities (e.g. thumbnail rotation, shadows etc.). Thus the layout is not 100% identical to modern browsers like Mozilla Firefox, Google Chrome, Apple Safari and Opera. IE9 however, being an actively developed browser by Microsoft (which supports some CSS3 specs), is known to have issues rendering this particular layout natively, which we're currently investigating. We strongly advise users whose site visitors are mostly coming from IE to possibly use a different gallery layout.

Bumber .. Thanks for the reply.
