<div><SPAN style="font-size:12pt;color:navy;">> It is most likely the way you are starting the second dialog.  If</SPAN></div>
<div><SPAN style="font-size:12pt;color:navy;">> you use execute(), the method will not return until the second</SPAN></div>
<div><SPAN style="font-size:12pt;color:navy;">> dialog ends, and your first dialog can not continue until execute()</SPAN></div>
<div><SPAN style="font-size:12pt;color:navy;">> returns.</SPAN></div>

<div><SPAN style="font-size:12pt;color:navy;">></SPAN></div>
<div><SPAN style="font-size:12pt;color:navy;">> You need to use popup() to start the second dialog.  The popup()</SPAN></div>
<div><SPAN style="font-size:12pt;color:navy;">> method returns immediately and your first dialog can continue</SPAN></div>

<div><SPAN style="font-size:12pt;color:navy;">That was the problem.. thanks again for your help.</SPAN></div>
