John, Thanks alot. It worked over here :) (of course!)
Sorry about the unformatted code sample - I've checked out the editor and can now do it.
I searched the forum and the web for events and console apps, but obviously don't understand something - as the events here work with this example...
My question is why the following doesn't work. Tracing it, it throws no errors, goes through the RaiseEvent but does not go through OnCellValueChanged; so I guess the event is raised but not heard. (It's a console application.)
