How to re-edit a text layer after saving xfc file and re-loading it?

I can only confirm Rich's findings. Layers named "Clipboard" are created when you Edit>Copy on one side, and Edit>Paste as new layer on the other, and this indeed produces a bitmap layer with all text information removed. If you drag the layer from the Layers list of the source to the canvas of the target, then it is transferred as a text layer and the text information is kept.
