RadioMenuButton Palette does not appear on second touch

[godiard]

TestCase:

• Download Write 89 [1]

• Install and open in a xo-4 touch.

• Open the Text toolbar.

• The last button, is the alignment button.

• Touch it one time: the palette will open.

• Touch in any place of the canvas or select one of the options, the palette is closed.

• Touch the button again: ERROR: The palette is not open.

• Try with the touchpad, the palette is opened every time.

• If we touch a first time, and later move the touchpad cursor over the button, the palette can be opened with a second touch.

• The same happen in other activities using a RadioMenuButon, like Fototoon, or the next Paint.

Simon said we should use PaletteMenuItem instead of MenuItem. A example of use is [1]
