This is an awesome extension and it work well on our website. Unfortunately I experience the same problem Jeroenla mention in his post.

SEO options enable will cause SectionEX misbehave.

Here is the detail for my observation:

1:: SEO enable (Admin page -> Global Configuration setting)

Under SectionEX option :: Menu and Pathway Behavior

When it set to Front page like article links :: ->
Page article title link did not point to the correct article.
For example::

SectionEX menu show Article Title :: How to install CamStduio on Windows but it actually point to how to install openoffice.org on windows. All titles did not link to the right articles
PDF icon and Print icon behave normal

When it set to SectionEx like Article Links :: ->

All article titles point to the right articles. However, joomla build in PDF and Print function will not work. It show 505 pages not found.

I would love to get this extension working with the SEO setting. If anyone comes across the work around for the issues I listed above, could you please share your resolution with us?

Thanks in advance for all your helps and suggestions.
