See: http://www.limesurvey.org/en/support/forums/2-design-issues/49594-set-box-text-input-width-for-other?limit=10&start=10#50709

My fix is to add a line to qanda.php to resize the receiving text box based on the value of $maxselectlength:

if (isset($maxselectlength) && $maxselectlength > 60)
{
$ranklist = str_replace("<input class=\"text\"", "<input size='60' class='text'", $ranklist);
$answer .= "</tr>\n<tr>\n"
. "\t<td align='left' class='output'>\n"
. "\t<table border='0' cellspacing='1' cellpadding='0'>\n"
. "\t<tr><td></td><td><strong>".$clang->gT("Your Ranking").":</strong></td></tr>\n";
}
else
{
[b]$ranklist = str_replace("<input class=\"text\"", "<input size='" . $maxselectlength . "' class='text'", $ranklist);[/b]
$answer .= "\t<td style=\"text-align:left; white-space:nowrap;\" class=\"rank output\">\n"
. "\t<table border='0' cellspacing='1' cellpadding='0'>\n"
. "\t<tr><td></td><td><strong>".$clang->gT("Your Ranking").":</strong></td></tr>\n";
}
