I'm not sure if this problem is new with version 5.0b (I came across it while trying out the new grouping support), or if maybe it's already known or I'm doing something wrong.

If I remove two events that originally were grouped together from a script and then undo the script (Ctrl-Z), the events are all created again, but not grouped together as they originally were.

For example, put some clips into your timeline (video and audio), and then run the following simple scritp to remove all events from you project:


import Sony.Vegas;
import System.Collections;

var q = new Queue();
for (var t in Vegas.Project.Tracks) for (var e in t.Events) q.Enqueue(e);
for (var e in q) e.Track.Events.Remove(e);



After the script is run, all events are gone. If you now undo the script, the events are here again... but the grouping is lost. If you move a video event, the corresponding audio event is not moved with it.

I'm not sure if thsi problem already existed in 5.0a and earlier, but at least in 5.0b, this seems to be there. It is not terribly bad, but worth being mentioned. It might be somehow connected with the new grouping feature of scripting (not sure though)

PS: Just tested it on older versions. The problem also exists in 5.0a and even 4.0e (the oldest Vegas version available to me).
