60. A determination is made as to whether the user has pressed
the mouse button down. If not, no computer event has been
generated. If the mouse has been pressed down, the CPU
determines if the pointer icon is located in the whiteboard area
60. If the pointer icon is not within the whiteboard area, then
the icon is not in a position of concern. If the pointer icon is
within the whiteboard area 60, the CPU obtains the mouse pointer
position icon location from the received packet and obtains alist
of the conference participants. Next, the CPU creates a packet
containing the pointer icon position location information (box
210) and sends the packet to each conference participant (col. 8,
line 57 through col. 8, line 19). If the CPU determines that the
pointer icon has moved, the CPU obtains the new position (box
220) and sends the updated information to each of the conference
participants (col. 8, lines 20-33). The CPU then determines if
the mouse has been released. If the mouse has been released, the
user is no longer designating a point within the whiteboard 60,
and the routine ends (box 230) (col. 8, lines 34-46). If the
mouse button has not been released, processing continues.
Figure 12 shows the steps followed when the sender's machine
detects that the mouse button has been released. When the CPU
determines that the mouse button has been released, the mouse
