Have only been able to test this on Windows 7 so don't know if it is the same on other systems. In all components there is a noticeable delay between right-clicking on the document and the context menu appearing. This is most severe in Writer (the delay is around 6 seconds), but affects all components (the delay is around 1 second in all components except Writer).
