Return pop-up from button blocked

Return pop-up from button blocked

I have a button on a create view that has worked consistently for quite a while.  All of a sudden, it is opening a new tab in the browser with the message about:blank#blocked rather than giving the return value.  When tried from the function editor, it is working fine.  I have checked my pop up blocker and the zoho domain is in the allowed list.  Does anyone know what is happening?
