Not able to select a part with cursor in solidworks composer

Why i'm not able to select a part with cursor. and if i did select the part using the design tree, i can't transform it. Basically i can't do anything othar than  rotate the view. Can anyone tell me whats going on in my composer. All works great before i upgrade into the latest version 2014.

Thanks,

Bhuna.
