Great point Lucky... it takes me 6-8 clicks to open some of these groups and find the actual element needed.
However, I am finding the worst thing, is you can no longer lasso and select some groups... and the undo and redo does not function properly within some of these groups.
Having groups can make things easier, but I have wasted so much time with the above I am going through and removing all groups. I would prefer to have the clutter in the timeline window than this waste of time and frustration.
As DB points out, this is happening within nested groups.
I pulled the groups apart and the lasso feature works as expected.
