XE2 delay in switching from code to form view

I am moving my apps from XE to XE2 Upd4.  One thing I have encountered is with many of my apps,  I get a delay when switching between the code view and form view.  It seems to be mainly apps with using smooth controls.  Also more pronouned with forms that have many components on them.
Any solutions? 

We have ourselves not noticed this here and this is the first such feedback we get.

We'd think this is rather an IDE and/or IDE/machine/install issue than something in our components.
Did you contact Embarcadero about this?
