Strange Occurrence with front page carousels

[Davyc]

On my home page I have a few carousels and they are doing what they are supposed to be doing except for one thing; once you hit the right slider arrow twice, you can't scroll back using the left slider arrow.  Any ideas as to why this happens?

With thanks
