Create a rounded rectangle or rounded square
The maximum X- or Y-axis radius length that the BlackBerry® Composer displays for the roundness of corners is half the height or width of the shape. If you type a value that exceeds half the height or width of the shape, the BlackBerry Composer processes the value as half the height or width, and does not change the values in the Inspector. The BlackBerry Composer stores the value and applies it if you resize the shape such that the value is less than or equal to half the height or width of the shape.
