Thanks.
Well, I fixed it. The problem is related with using a DIV as row container and applying the attribute "display: table" to it. This bug is documented.
Just replaced it by a one-cell table.
The other bugs... well I don't know why IE gives an error and doesn't round the corners. I'll work on that later.
The xLanguage module not cleaning language tags inside a form is a unpleasant surprise, but i'm sure i'll fix it. Perhaps reading the smarty variable for language or something like that.
