Shift+End and Shift+Home do not select text in 8.7.4

Hi,
Amaya 8.7.4 in W2K: with the insertion point in the middle of a text line key
Shift+End: nothing happens. It should select the text from the insertion point
to the end of the line.
Similarly Shift+Home also does nothing, it should select text from the begining
of the line to the insertion point.

If you set a paragraph bigger than the window then you'll notice that
Shift+Home/End works like Control+Home/End.

Regards!
