Not sure if anyone else has had this within PR1.2 yet but these are some of the problems I've encountered already.

1. Widget Customisation:
once the "Done" button is clicked it remains highlighted but nothing happens for around 1-2 minutes. This has happened EACH time.

2. Menu Customisation:
once the menu has been customised pressing the "Done" button results in the menu resetting to the original menu set-up.

I'm currently using the latest Power-Kernel overclocked to 900mhz, not sure if this is causing the problem.
