Dreamweaver Split View

I just upgraded from Dreamweaver MX to MX 2004. When I make a change in the
code while using "Split View" (code + design views open) and save the file, DW
MX would update the design screen so I could immediately see the change I made
while typing around in the code window. Now with DW MX 2004, after saving I
have to click in the design window to see the change get updated. Any idea how
to fix this? Is it a setting I can change or a bug?

Thanks!
