When I use this new register button function with Use Ligne for Button Width active, it is changing the size of my buttons. I create a 24L and 32L button and set the widths in the register dialog, but when I open the property editor, the width has been changed- the 32L is now 50 and the 24L is now 38. To test, I disabled the Use Ligne (and my Unit system is Inches, and now the register dialog is showing the width as being in Inches but the thickness in mm. I entered a value of 20 for the width, and when I open the button, the width displays as .787 inches (which would be the same as 20mm), which means the register dialog is taking a value of mm, not inches, despite a display value of inches.
