Old post I know, but just came across it because I am having the 'height' problem with an unusual setup; I am using Interspire Shopping Cart that uses a <wrapper> tag that PHP generated pages are placed within. The MachForm iframe creates a huge gap (almost 30px) at the bottom of the page, just above the footer. This works great when nothing is completed on the form, which will probably never happen, since it allows all the error messages to be displayed and still see the submit button.
I know it is impossible to develop for every type of Web site, but it would be great if some type of 'auto' height adjustment was built into MachForm.
In the interim, does anyone have suggestion how to implement this adjustable height fix into my setup?
