Google Chrome display issues

Hi,

Over the weekend I added a fixed bottom bar to to a site of mine, which contains a transparent PNG slightly overlapping the main content.

It displays correctly in all modern browsers, but I've noticed an annoying issue in Chrome.

Sometimes (randomly it seems), when you scroll up and down the page, and then hover over a link before moving your cursor off the link, the link preview in the bottom left hand corner of the browser will "stick". Eg. when normally you would expect the link preview to disappear, it remains with the root domain of the site showing "onedirection.net".

Can anyone else confirm if it is doing this? I've no idea why it would do this, as it seems purely a Chrome issue.

Also, a second issue I've noticed as a result of the new bottom bar is on sidebar, the grey headings of each box seem to become corrupted when you scroll up and down (they should be solid mid-grey colour, but I keep seeing a lighter grey colour running horizontally through them.

Can anyone else also confirm this? I've tested it on two different PC's both with the latest version of Chrome (17).

The site is OneDirection.net (won't let me post links)

Cheers,

Chris.
