animation of selection with mouse

Open the BASIC IDE and show a macro in the edit window. Select a line of the
text. Notice that the entire window repeats to refresh, while you drag the
mouse.

I do not own a screen cast application, but can only take single pictures while
moving the mouse. But this pictures show clearly that the edit window content
is refreshed several times, see attachment.
