I've installed the latest version of Contact Form 7. I've tried testing it by omitting some required fields and seeing what happens when the validation error messages appear. This seems to break my layout and the page flickers when I scroll in every browser except Opera.
I copied the source code from the browser and pasted it into the the W3C validator and got no errors. There is nothing unusual about the CSS either. I also tried saving the source code as a separate file in Wamp and when I open this in Firefox it renders the page perfectly with no flickering and no broken layout.
This is really puzzling me. Has it something to do with conflicting scripts? I've been messing around with this for hours and can't fix it. Any help would be greatly appreciated. Thanks in advance.
