Using Excel in Office 2000, never had any problems until last month: Once I
click the cursor in an Excel cell, it will not move to a different cell, it
only moves as if I am dragging it and highlights all the cells as it travels.
Also, I cannot them use any of the top row of tools, etc. including Exit.
Tried downloading patches and service packs to no avail. Happens with both
touchscreen and mouse, and with left and right clicks.
