I'm coding a windows program which is a WYSIWYG form generator.
In a very simple test I placed a fieldset and dropped a checkbox and a text input field onto it.
The generated HTML looks fine when I read it, but it displays wrongly in Firefox, MSIE & K-meleon (which I think has an FFF engine). The fieldset height does no seem to be rendering correctly.
I also tried removing the height attribute to see if the fieldset would wrap around its child controls, but it looked the same in the browser. Probably a mistake in my HTML, I guess, but I can't spot it...
