Form: my form freezes the web browser

Why in the middle of my form being built my tab for Jotform.com freezes and can not load, use page, and have to start a brand new form. Are you going

Ichecked your form and I was able to replicate the issue.

When I opened the cloned form, I was able to replicate the issue.
