Table Scroll bar is locked in chrome

[divecall]

I have an issue with a table scroll bar in google chrome only. The table scroll in all other borwsers work fine but in chrome when the table scroll bar appears it just locks in position, it cannot be moved unless I alter the zoom of the browser window, then the table scroll bar moves.I have an application http://helios.hud.ac.uk/u0867587/Mobile_app/QandATable2.phpIf you open up the embedded version of the jsfiddle: http://jsfiddle.net/2SJFt/embedded/result/ in google chrome and perform the same steps to get the scroll bar to appear, then it does perform a scroll straight away, but I am assuming that because it is technically in a jsfiddle that, that is why it is performing the scroll straight away.The scroll bar for the table is done by simple css:\[code\]#qandatbl_onthefly_container{ width:100%; overflow:scroll; max-height:500px;}\[/code\]
