Hi Myatu :)
First, thank you very much for all of the work you have done on such a wonderful plugin. I would love to see this dragged into the core of WordPress, it is fabulous.
I am having an issue with a premium theme (themify/magazine). I am a little stumped on why the backgrounds are not appearing more than 45 pixels high.
Here is the screenshot of the options, perhaps I am doing something wrong, but I think it could be the theme and some CSS setting that I am not seeing (been stuck in inspector all morning!)
