Pressing any key on the keyboard, changes default cursor to Text cursor when the mouse is on the scrollbar (horizontal & vertical) & its intersection point.

Step to reproduce:
----------------------
1) Run the attached program. You will see a frame containing textarea & scrollbars (horizontal & vertical )
2) Move the mouse on any scrollbar or intersection point of the scrollbar. You will the default mouse cursor.
3) press any key on the keyboard. observe that default cursor is changed to text cursor.If you see the same then the bug is reproduced.

This works fine in Tiger FCS b64 & Mustang b20 , but fails in Mustang b25 onwards.
Hence this is a regression. There is an another bug similar to this bug (6429174) which got fix in Mustang b91. I tested even in the Mustang b91 PIT build , but still the bug is reproduced.
