a bug was found in the footer which caused a issue with the style drop down menu.
This has now been fixed.
You can either download again or apply these code changes to the footer template:
Code:
<select name="styleid" id="ressel" onchange="switch_styleid(this)">
<optgroup label="$vbphrase[quick_style_chooser]">
$quickchooserbits
</optgroup>
</select>
And change it too:
Code:
<select name="styleid" onchange="switch_id(this, 'style')">
<optgroup label="$vbphrase[quick_style_chooser]">
$quickchooserbits
</optgroup>
</select>
