Hi, I have now finished implementing undo/redo functionality. I don't think there are any critical bugs :-) but let me know if you find any.
In particular, the following operations are covered : * adding/removing clips from the timeline. * Resizing of clips * Moving clips around * Selecting/deslecting clips. A minor issue: * You will notice that the timeline is very "jumpy" at the moment - with clips flickering when you start and stop moving them or selecting them. This is due to a modification in the way I update the timeline display, and should be fixed soon. Cheers, Jason -- Jason Wood Homepage : www.uchian.pwp.blueyonder.co.uk
