The mobile version may well be OK on a small screen, but is pretty dire on a large format tablet, where by default I (and probably anyone else with a big screen tablet) will set the default to the "normal" version. It's when the browser (in my case Firefox) is set to default to the big screen version (because the tablet has a big screen, so it's daft to just have a "letter box" mobile phone type view) that the fixed position header overlap seems to create a problem. The mobile skin isn't really usable on a big screen tablet, unfortunately (this may well be why I had problems when I tested it out using my wife's big screen iPad, too, perhaps).
This thread consistently has the lock up problem with the rotating black arrows at the bottom:

This post illustrates the big blank box issue, where some embedded content doesn't display in the post, but does pop up if you quote it, for some reason:

Getting a screen grab from the tablet to show the fixed forum header blanking out the posts which scroll behind it is a bit challenging, but I'll see if I can get one if it may help sort things out.
Finally, for some reason the Private Flying sub-forum is still in the older format, it seems:

I hope the above is useful, and I do appreciate the work that goes on behind the scenes to keep this forum going!
