"jquery is not defined"

I upgraded to the latest JQueryPlugin, and since then the raw edit and wysiwyg edit functionality does not provide the editing pane.

In firefox, I see the following javascript errors.

jQuery is not defined

I have tried adding JQueryPlugin to the start of the PluginOrder, but that made no difference. What can I do to allow these plugins to use JQuery? Everything was working fine before the plugin upgrade.

thank you,

Chris.
