Support Lag in displaying of apps on home screens

view story

http://androidforums.com – Anyone else experiencing lag in the loading of the apps on the homescreens when pressing the home button? It doesn't happen every time but when it does it can take two or three seconds to display the apps on the given screen. It's pretty frustrating!! At first I though it might have been down to excessive widgets but I've removed most of them and it's made no difference! Could it be a rogue app? Any help would be awesome!! MoS (General)
