When working in DW in Split View, when the user clicks into the Design View
window the view automatically updates the view if code view has changed.

Can i intercept this? Does it call a specific file or menu command that i
would have access to?

The reason:
We use DW as a stand alone HTML editor and some of the files we work with are
extremely large and each time a change is made in code view and tusers click
into design view it auto updates the deisgn view and this could end up taking
some time. i would like to manually control this if possible?
