The point is, this problem could occur in ANY upright but is more likely in an old one.</FONT></SPAN></DIV> <DIV><SPAN class=715383417-21032005></SPAN><SPAN class=715383417-21032005></SPAN><SPAN class=715383417-21032005><FONT face=Arial></FONT></SPAN> </DIV> <DIV><SPAN class=715383417-21032005><FONT face=Arial>No purchase required to enter. </FONT></SPAN></DIV> <DIV><SPAN class=715383417-21032005><FONT face=Arial></FONT></SPAN><SPAN class=715383417-21032005><FONT face=Arial></FONT></SPAN> </DIV> <DIV align=left><FONT face=Arial size=2>Alan R.
