form layout messed up in (older) IE browsers?

I have a registration form on my site (www.relativerotationgraphs.com) that uses cf 4.0.1 it works fine in basically all browsers but I now get messages from users that the form is messed up on their end, fields being misplaced and mis-aligned. I can re-create the issue when i use IE 9 AND tick compatibility view. In that case the form gets messed up. In regular mode and FF, Chrome etc, it all works fine.
Any ideas about this or potential workarounds, settings I may be missing ?

Hi,

The registration form on your site appears to be built with jForms not ChronoForms. I can see a layout problem if I view the form in IE11 set to IE7 mode.

Huh🙂 ...... This is really embarrassing ..... but you are right I had the reg form setup in CF but at a later stage switched to ajax register, my other 2 forms ar CF forms and they do not have any problem🙂
just bought you a coffee/beer for your time ..... pffffffffffffffffffffffffffff
