NIS 2010 REFUSES TO PERFORMANCE FLIP

My NIS 2010 has recently been upgraded from version  17.0.0.136 to 17.5.0.127.Problem is the Performance Interface no longer flips like it use to. It sticks for a second or two before it  displays the reverse side of the product,

(without the flip).

 

Once on the reverse side of the interface, the HOME option  has disappeared, allowing you only to close down the interface from the X/Close icon at the top.

 

Appreciate any help ideas???
