JavaScript isues in Chrome and Edge

We’re using v7.7.3 and two users report that they can’t get “Advanced Search” to open or close when using Edge or Chrome (latest versions of both) for Windoze 10.

But on WIndows 8, Chrome works fine for me (same version).
Without being able to duplicate it on my machine, and them being non-programmers, I don’t know how to track this down.

Has anyone else experienced this?

Thanks

H
