Error adding new record using IE 11

Hello:

I’m testing vault with IE 11 on dhtmlx.com/docs/products/dhtmlx … cords.html
I can’t add new record as you can see on file attached




I’ve downloaded vault component and I get the same error.

Thanks and best regards.

Is there any new version of DHTMLX Vault that can solve this IE error?

Using DhtmlxVault component I get this warning:

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check xhr.spec.whatwg.org/

Could this be the problem with IE11?
