Image scroll problem in IE

The image opens correctly, but when trying to advance to the next image it loads and never scrolls… (happens in IE only)

also, when you close that loader and open any image again, the scroll works..

(scroll down for the FancyBox images)

Any suggestions how to fix this would be appreciated!
