Split at selection

When I do a split at selection (splitting a text item into two) it takea few seconds (about three or four) to implement the command. I don’t know whether that is a bug or normal.

EDIT - it’s more like 7 seconds now. Project is less than 5,000 words.

I am now up to close to 7,000 words and split at selection is taking about 17 second to create a split/new text item.

In contrast, creating a new text item by highlighting one item in the binder and pressing return creates a new text item immediately.
