Hmm, this implies something else.
Or I think the problem is in the skin itself, or you haven't set the display resolution properly. It's also possible that you have too many active ux files on such a small screen.‚There is an overlap between them.
And when I say small screen, I don't mean physically small, but rather a small resolution.
On such devices it is best to use the basic package and add a few uxes as needed.
