ok, mine never flashes, everytime there is a new PM, it just goes to a different color then the rest but doesn't flash, why?
This is what I have in my Template:

PHP Code:

<tr id="cat">
    <td id="pmBox" bgcolor="{categorybackcolor}" colspan="6"><a href="private.php?s=$session[sessionhash]" title="Click Here to Open Your Private Messages $inboxname"><normalfont color="{categoryfontcolor}"><b>Private Messages</normalfont></b></a></td>
</tr>
<tr>
    <td bgcolor="{secondaltcolor}" align="center" valign="top"><img src="{imagesfolder}/$lightbulb.gif" alt=""></td>
    <td bgcolor="{firstaltcolor}" colspan="5"><smallfont>
    <b>$bbuserinfo[username]</b> - You have $newpm[messages] new message(s) since your last visit.<br>
    (You have $unreadpm[messages] unread messages and $allpm[messages] total messages in all your folders.)</smallfont></td>
</tr>
<script language="JavaScript">
<!-- Begin
$pmblink pmBox.bgColor='#1D6AA0';
$pmblink setInterval("Timer()", 500);
$pmblink x=1;
 function Timer() {        x=1;
        set=0;
    }
    if(x==1 && set==1) {
        pmBox.bgColor='{categorybackcolor}';
    set=1;
    if(x==0 && set==1) {
        pmBox.bgColor='#336D95';

        x=0;
        set=0;
    }
}
// End -->
</script>
