iOS6 webkit timer bug workaround
(function (window) {
// This library re-implements setTimeout, setInterval, clearTimeout, clearInterval for iOS6.
// iOS6 suffers from a bug that kills timers that are created while a page is scrolling.
// This library fixes that problem by recreating timers after scrolling finishes (with interval correction).
// This code is free to use by anyone (MIT, blabla).
// Original Author: [email protected]

@kTmnh, My site is not yet live. So unfortunately cant review my code now. What I am having is a slideshow of images. I am using cycle 2 for this slideshow. All my images are given links to their respective pages. But I am getting issue in the slideshow after a 'L' shaped swipe. And I added this js to fix this. It worked fine after adding ur js. But unfortunately when i click the image, its not redirecting to its page. I am in a critical situation :( .If its not working, i need to use some other plugin for this slideshow. :( But I would like to use the awesome cycle 2 itself. Is there any way to fix this issue?
