Sometimes after rapid clicking on RadSplitButton, its DropDown stops closing when the user clicks outside it.

Pressing backspace key in ComboBox element added to a RadDropDownButton closes that popup box and doesn't allow you to do any modification

You can't handle the KeyDown event for RadRadioButton if the key pressed is Enter.

You can't handle the KeyUp event for RadCheckBox if the key pressed is Enter

To reproduce: Add a RadRadioButton to a form. Add a Button which opens a OpenFileDialog. Open the dialog and position it on top of the RadRadioButton so when you double click on a file the mouse cursor to be exactly over the RadRadioButton. Double click a file and you will see that the RadRadioButton is checked. This behavior can be changed by changing the ClickMode of the RadioButtonElement but setting it has no effect.

To reproduce:
- click a RadCheckBox with the right mouse button and you will notice the the state of the checkbox is changed.

Workaround:

public class LeftCheckBox : RadCheckBox
{
    protected override void OnMouseUp(MouseEventArgs e)
    {
        if (e.Button == System.Windows.Forms.MouseButtons.Left)
        {
            base.OnMouseUp(e);
        }
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadCheckBox).FullName;
        }
        set
        {
        }
    }
}
