Getting the same thing with Safari, but works properly with Chrome.
Since there is new window that pops up in Chrome, it could be related to blocking pop-ups perhaps?
Most interesting. I verified that Safari had the box unchecked for blocking popups. But apparently it still was. I tried Google Chrome and it blocked the popup by default, but I changed the preference and then it worked. I could never get it to work in Safari. Hopefully FileMaker will improve on that since many of us use Safari as our Web Browser.
Thanks for teh tip, wimdecorte! You solved the problem!
