Some setting needing to be changed ?
I have Edge browser installed on my win 10 system.
A couple of blog posts by SeedCode (links below) might explain what is going on. It looks like Soup regular @MonkeybreadSoftware may have provided the solution.
Another solution, if possible, might be to convert any FMP URL calls made by the webviewer into using the FileMaker.PerformScriptWithOption feature, instead.
Hope this helps.
Thanks a lot @steve_ssh
Worked like a charm.
Thanks a lot @MonkeybreadSoftware.
It was originally your idea of how to solve this.
