Desktop/PCMode link does not seem to work with VB 4.1.3, every time user switches to Desktop Style, clicking any forum link causes style to switch back to Mobile/Lightweight style. I just changed default style chooser to have 'none' option with value '-1', similar to what VB mobile style uses to switch back to full style.
Code:
<setting varname="ls_default_style" displayorder="20">
<datatype>free</datatype>
<optioncode>select:eval
$options = fetch_style_title_options_array();$options = array('-1' => $vbphrase['none']) + $options;</optioncode>
</setting>
This works alright, please let me know if there is better fix.
