the image we're talking about is
http://shoutbox.menthix.net/images/tdbg2.gif
That has indeed a white line on top. But as you can see in all the other lightblue bars, that white line is meant to be part of the 3d border effect and should be totaly on top in the background to create the 3d-border...
Now on the user CP there goes something wrong, so that the image is put twice in the table, once on top (you can see that) and once in the middle again and thus creating that line....
I suspect it is the double use of the "trow1"-styleclass....
In short: no it wasn't intentional and it is a small GUI-bug....
EDIT:
html code taken from
http://shoutbox.menthix.net/private.php for the bottem "Jump to folder"-bar:
<table cellspacing="0" cellpadding="0" border="0" width="100%" align="center">
<tr>
<td class="tborder" colspan="2">
<table border="0" cellspacing="1" cellpadding="4" width="100%">
<tr>
<td class="trow1">
<table border="0" cellspacing="0" cellpadding="0" width="100%">
<tr>
long line 1
long line 2
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>
</table>
long line 1 is:
<td
class="trow1"><font size="1" face="verdana,tahoma,arial,helvetica"></font></td>
long line 2 is:
<td
class="trow1" align="right"><font size="1" face="verdana,tahoma,arial,helvetica"><b>Jump to folder: <select name="jumpto"><option value="1">Inbox</option>
more options here</select><input type="submit" name="hop" value="Go!" /></b></font></td>
Parts in
blue are the ones that cause the second white line....
