Diagonal (straight) line layout issue if there is end text
See attached file,
Click on the line that has been added to the TAB from the line palette. Create a diagonal line with it by dragging the end handle. Reset the line to horizontal and add some end text to the line – for example, a right angle-bracket to simulate an arrow. Now try to make the line diagonal again by dragging the handle: You can't! The line does not draw and the text remains in the horizontal position.
