System: Windows 7 64-bit with Internet Explorer 11, FileMaker 14 Adv. 14.v5
I struggled with this for a full day until I found the reason. Frustratingly, it seems that the Web Viewer in FM 14 runs in IE9 compatibility view, regardless of any setting in IE 11.
To verify this, load up the following address in a Web Viewer and in a browser window in IE 11.
I attach two screenshots, the one with the compatibility view detection is from the Web Viewer.
I really hope someone has a solution as my code does not run in IE9.
<rant>I never could imagine that FM would have such an arbitrary restriction, they always say that the Web Viewer uses the engine of the system. Well, it doesn't, at least not without issue. </rant>
