I say difference because I am not familiar enough with code to know if it was intentional with the upgrade. But I am seeing the following after upgrading:
1. The registration form field are spaced very far apart in Chrome but look fine in IE.
2. Captcha works in FF and Chrome but not in IE7, 8 or 9.
Can some please comment on whether this is intentional and if not please let me know how to correct it?
