[Plugin: Visual Form Builder] Alter form width

Hello,

Can anybody tell me how and where to alter the code to reduce the width of the form.

I think it’s set to auto but it’s a bit too wide for some browsers and it’s forcing the left hand side site navigation underneath the form.

It all works fine on Firefox and Safari but it’s making the page display funny in Explorer.

I think reducing the form width will solve my problem, the page is at;
