[DevExpress Support Team: CLONED FROM T184688: The function copy / paste stops working when in the form there is a LayoutControl]
It has not solved the problem.
I add project with 13.2 version, which works correctly.
Select Form1 and xtraTabPage1, layoutcontrol1, edit, copy.
To the right of layoutcontrol1, edit and paste.
Select xtraTabPage2, edit and paste
Go to Form2, edit and paste.
It works correctly
Change the Assembly version to 14.2 or 14.2.14345 and follow the same steps.
Works only the first step.
Others fail.
