in standards-based browsers (firefox, chrome etc) there's an error w the html for the previous and next arrows on day, month, and week views (may have been corrected in a later version). They cause the link to begin a line above the words/arrows, in my case this means mousing over created a tiny dot above the links.

to fix that, go to the include files for main_monthnavpreviousnext (and day and week) and flip the <p> and <a> tags - as it's set up, it's something like <a [link]><p>previous</p></a>. it should read <p><a [link]>previous</a></p>
