  <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2"><B>Version 2.81.2 (October 
    25, 2002)</B><BR>
    - The components prevented Windows for being shutdown. This bug fixed.<BR>
    <BR>
    </FONT></LI>
  <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2"><B>Version </B></FONT><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2"><B>2.81.1 (September 
    28, 2002)<BR>
    </B>- Bug on proportional scaling of the image fixed.<BR>
    <B><BR>
    </B></FONT></LI>
  <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2"><B>Version 2.81 (September 
    26, 2002)<BR>
    </B>- There was a memory leak on loading large images (more than 1MB) to the 
    control, which is fixed.<BR>
    - Race condition problem of the thread in TDBPicShow fixed.<BR>
    - New event OnGetGraphicClass added to TDBPicShow.<BR>
    - Algorithm of image rotation optimized.<BR>

  <LI><FONT FACE="Verdana, Arial, Helvetica, sans-serif" SIZE="2"><B> Version 2.80 (September 
    10, 2002)<BR>
    </B>- Control's thread optimized. In threaded mode, control does not call 
    Delphi Synchronize function anymore to synchronize itself with the main VCL 
    thread. As the result, no more deadlock, faster thread termination, lower 
    CPU usage, and smoother transitions. However, because of this change, the 
    control cannot be compiled as non-windowed control anymore.<BR>
    - Now changing the value of <I>Manual</I>, <I>Progress</I>, and <I>Reverse</I> 
    properties at the last step of transition takes effect.<BR>
    - New method <I>OnStop</I> added. <B><BR>
