IE asks for security certificate approval twice for self signed applet
===

Using RXTX and Java applet, I have created an applet to dial a telephone number.
Its wokring fine ,but when browser loads the applet , security certificate approval pop up comes twice.
when I click on RUN when the security pop up comes first time and why does the pop up come again.

my applet is in click2callapplet.jar and uses RXTXcomm.jar both of which are self-signed by the same certificate.

log of the java console is attached below. Any kind of help would be kindly appreicaated.
