Xander,
I tried this but it always seems to return true (for keyboard messages) in
IsDialogMessage, but does not shift the focus on the TAB key press. I am
doing this in D3 using IE4. It could be that the IE4 control is in an MDI
child window - I will try using a non MDI window and a bit more
experimentation.
Dennis.
