hey wayne,
the 2 different url's where coming form the fact that you have 2 different menu items and depending on the item easyblog was generating the matching url.
I changed this behaviour in your easyblog backend -> settings -> seo to always use the id of your easyblog menu. now if you take a look at it, regardless in which section you are, the easyblog links all have the same yoursite../easyblog/entry/title format as you wanted.

hope that helps and have a nice day
