Love it but has ipad problem

I love this plugin – only 4 operating files and it does more than notification bars with 4x the files! But there is one problem I haven’t been able to sort out – on the ipad, the bar frequently (but not always) shows up behind the Safari address bar. This seems to happen only in the horizontal view; the vertical seems to behave the way it should. Any suggestions?
