Might be something to do with how Apple interprets 'hover over' vs 'click on' with a tablet. You can't have both. Your finger is on something or it isn't, there's no equivalent of 'hover' with a tablet.
In which case, it's an Apple problem.
I don't have an Ipad. Perhaps someone who does can chime in with how theirs works and if they have the same problem.
