Hi all,
I've found that 7.3.3.3 formats boxes well. i.e. The Email box has rounded corners and shadows.
Versions 7.3.4, 7.3.4.1 and 7.3.4.2 don't seem to format the email box at all (no rounded corners or shadows).
I noticed the [tel] tag wouldn't work with 7.3.3.3, so I'm capturing this info using the [text] tag just now. I'm going to assume [tel] was introduced with 7.3.4.
I hope this helps.
