I am unable to insert/overwrite while not focused on Source monitor. It was possible in PPro 2. This means that when I am moving between cut points in Timeline or Program monitor and want to insert/overlay at a certain point, I must then switch to Source monitor and press comma or dot (keys for insert or overlay) or use mouse. Not very productive.

Why is this? It`s happening on XP as well as Mac OS. I cannot imagine this being useful, so it`s most likely a really stupid bug. Any comments?

No one? You all guys really use mouse all the time?

I am a mouse user, but since CS3 now has shortcuts to move from panel to panel, is it really that much more work?

Yes it is, and it breaks my workflow from PPro 2.

When doing three of four points edits its sometimes very helpful to be able to do inserts/overlays directly from the Program Panel or the Timeline Panel (like in PPro2) and not being forced to *only* use the Source (CS3).

No mature editing suite should deliberately force its user to relearn the most principal and basic features. I like CS3's new ability to switch between panels via keyboard, though.
