Want to group some clips to move them but edit/group/create new is greyed out. Individual clips can be removed from a group (although I haven't grouped them), but even when each is removed from the unknown group they cannot be grouped. This is new to me. What's going on?
Ah, indeed! Dragging across the group of clips isn't the same as clicking on each and then telling Vegas to form a new group. I would have insisted that I'd done it that way previously, but very clearly not so. So click 1st, shift click last clip and that may be called a group. Guess I've always done it that way -- until this afternoon!!!
I was able to reproduce your issue but it was because I clicked one of the events once to often after I had selected it, thus deselecting it. There should be a deep blue-grey color around the video event when it is selected. The border is white when deselected.
