I have this confirmed on both Windows and Mac using Firefox 11: the left side of the border around my form goes all the way out to the left side of the browser.
How it should be:
On all other browsers it looks ok. And strangely enough: all other Gravity Forms on the site looks ok. It's just this one:
that screws up.
Does anyone have an idea what might be wrong? I use a theme called Modernize, but if that was the culprit it ought to break all browsers and all forms, wouldn't it?
Any help is most appreciated!
