Thanks for the suggestions, Damon.
No joy. Had tried the filter/show all trick before submitting question. Tried it again, today, along with various browser zoom in/out settings.
Also, yesterday, I tried several different browser emulations (Edge, IE11, IE10, IE9). I've got a resource in Germany with same issue - we are the two that are experimenting with this feature, as its not currently utilized by our company.
So, perhaps we are into the uncommon ways?
