Just found this bug
If you have a multi value choice field on any form then it is now no longer possible to select the check boxes.
All the best

Thanks Alexander, I did revert back to 1.0.14.0 to get it working. Seems like the form somehow changed since the form I created with 15 still had the same issue even when I was using 14. I have since deleted it and recreatd in 14 and all is good.
Best regards /Marcus
