<DIV>Thanks Daniel,</DIV>

<DIV>You are right, after I add ellips, the maplab does not crash, but I still could not see the any map. Is it possible my OGR connection to mapinfo tab file not corrected? Any suggestion?</DIV>
<DIV> </DIV>
<DIV>When I use info tool in preview click on the blank map , the error message is " Fatal error [MapServer Error] msProcessProjection(), projection not named in C:\ms4w\apps\maplab-2.1\htdocs\common\wraper\map_session.php on line 841</DIV>

<DIV>Thanks </DIV>
