I an unable to work out why I am unable to type in a font size. I have an existing Text Layer. I double click the layer to activate the Text Edit mode, which highlights the text. I then highlight the font size in the tool bar. First, I am unable to delete said font size value. Then, when I try to type over said font sive, the numbers appear in the text layer. If I have the text still highlighted, the numerical input replaces said text. If it is not highlighted, the numbers are inserted. I then try and delete said text just entered, which I cannot. All the while the Font Size text box is highlighted and active, although the highlight appears Grey.
