Form freezes when I try to add a new language and update translations

I am having trouble with adding Spanish to my form. The form is being unresponsive when I try to edit the Spanish translation, and it isn't saving my work as I update translations. I keep having to start over. 

I have checked your JotForm and see that the Spanish language is already added and 3 pages of your JotForm is already been translated. I have cloned your JotForm to my account and see that the languages window opening and the translation is a little delayed. This is due to the number of fields on the form. It is taking a while to process the information on the browser. Please be patient while the translation is being updated after clicking on Save. The browser may become unresponsive when we try to force the browser by clicking other fields while it is processing. Also, please try closing other instances of the browser and see if that helps.

Hope this information helps!
