Embedded Worksheet Display Issues

I have a worksheet I've embedded in a web page using code created from Skydrive.

I have selected "Hide Row and Column Headers". They are hidden, but there is still a mystery line on the left and top of page I can't seem to get rid of, almost looks like a smaller representation of the headers. This is visible in Chrome, IE, etc.

Second issue... in Chrome, if I a scrolled down on the page at all, selecting a cell automatically brings you back to the very top of the page. Very annoying.

Any suggestions would be appreciated.

Thanks!
