Hi Jeff,
I'd expect it to work. It is documented as doing so.
https://4js.com/online_documentation/fjs-fgl-manual-html/#fgl-topics/c_fgl_menus_004.htmlThere has been odd issue many years where it would popup in the wrong place
https://4js.com/support/issue/?product=GBC&stat=&fixed_in=&words=popup+menu&Search=Search so I'd wonder if it was appearing off screen or is similar to some of those prior cases.
Suggest you try the example in the documentation, and raise a support call where you can provide more details.
Reuben
