After trying to figure it out myself I came no further than to identify the problem, but I was unable to fix it. Luckily I remembered Arshem had mailed me a couple of days earlier saying he knew a thing or two about web programming should we need help. Well, he may not have expected to be called upon so quickly, but I called upon his aid.
And voila!
Just a couple of days later our guild popups now works beautifully on mobile devices too.
So big thanks for that Arshem!
Watch it or you might become recruited as a wizard sooner than later...
