IE8 Transparent background can not click the problem

Recently developed the site, the demand is three one screen, 1 and 3 can only see half, 2 display in the middle, no arrow button.

Because previously wrote a plug-in with front and back buttons, thinking about how to change in this, so the front and back buttons to remove the background, positioning in the 1 and 3 position to achieve the click before and after,

Find the button in the IE8 in any case to modify the level, buttons are not, so Baidu, later learned that this is IE bug, transparent background elements will cause the Click event to expire. Very sorry.

So go back to modifying the script or adding PNG with transparent background.
