@Quantnet - You could try editing the navbar template and replacing:

<if condition="$vbulletin->options['mo37_default_style_link']==1">
<a class="navbar" href="{$vbulletin->options['mo37_navbar_home']}?$session[sessionurl]styleid={$vbulletin->options['mo37_default_style']}">{$vbulletin->options['mo37_default_link']}</a>
</if>

with

<if condition="$vbulletin->options['mo37_default_style_link']==1">
<a class="navbar" href="{$_SERVER[REQUEST_URI]}&amp;styleid={$vbulletin->options['mo37_default_style']}">{$vbulletin->options['mo37_default_link']}</a>
</if>

There may be some issue I'm not sure of (you *should* in theory clean all server vars before using them, but this *seems* safe (insert wordy disclaimer here) - use at your own risk, if you have knowledge of such this - you input is welcome!
