Blog pagination links and URLs issue

Been playing with this plugin for a couple of days, and enjoying it.

However, I’m having an issue with blog archive pagination. Whether I use a pagination plugin like WP Page Navi or the default WP next_posts_link() and previous_posts_link(), it’s the same effect. The first time one of the pagination links is clicked everything is fine. But from that point on any pagination link has a query appended to it, of the form:

http://mysite/category/uncategorised/?_=1362933226369

Each subsequent click of a pagination link increments the number by 1.

How to disable the appending of this query?
