Greetings,
I have noticed a bug with Facebook popups repeatable as following steps, this happens with Google Chrome Browser (latest stable/public version 18)
1. Make a Facebook Like button using Addthis with "Recommend" word (fb:like:action="recommend") (also you can use Send button)
2. To see it better, place an image beneath the button...
3. When you click recommend button or send button, Facebook popup asks if you want also to share (For recommend) or simple User Input from send button...
But while it works in IE9, in Google Chrome, popup starts to continuous flickering, goes transparent or behind other elements (such as image we have placed beneath) , goes almost unclickable with other elements around....
You can see this in action on Addthis web site: https://www.addthis.com/features/facebook-send-button
There, popup goes transparent and if you had any image behind it, you would see it is unclickable...
If you don't include addthis and place recommend button with code just from Facebook (be it normal tag or FBML), it works, no flickering or transparent issue, however AddThis does not count them ofcourse.
With Chrome over 45% of users of our site, it is important problem for us. I just wanted to report that problem and get information about if any ETA on a fix.
Thank you in advance...
