Since upgrading from 2.29.00 to 2.31.01 my window sizes do not remain the same size after logging out and logging back in to the panel. I see there is now a "Lock" button. It is hard to tell what is being locked. Sometimes there is a large blank area below the last extension button on the screen which can be removed by collapse and reopen. Or by manually adjusting the size from the corner resize icon. But nothing stays the same after closing and reopening. Always I am having to readjust the screens. Especially the extension screen that have the most buttons. Moving screens around will produce a large area below it that is not filled and remains white in color unless you manually move the window or uncheck the locked button and collapse and open. Am I missing something? What can I do to lock my layout the way I want it?
