Hmm actually it doesn’t work. Because when I activate the Lytebox or Fancybox viewer the problem repeats. When I select none it just works.
Hmm since I noticed another error with the plugin I completely removed it from my system and re-installed it. This time everything seems to work.
First question:
I use Ubuntu 10.04 and checked Windows XP.
Second question:
I checked the source from both the page without the plugin and with the plugin. And with both I do see a: <script type='text/javascript' src='/wp-admin/load-scripts.php?c=1&load=jquery,utils,quicktags&ver=b50ff5b9792a9e89a2e131ad3119a463'></script> Which suggests, I think, jquery is loaded.
