Expected behavior: I move the mouse over an link in pumpa, and the full url is displayed at the bottom of the window.
Actual behavior: Works sometimes but other times the displayed url is not the one the mouse is over.
Analysis: There are two kinds of links; links inside posts and links that pumpa makes to eg, people's names. If I first mouse over someone's name, and then move the mouse to be over a link inside a post, this is when pumpa keeps displaying the old url, rather than showing the new url I moved the mouse over.
Certain mouse movements clear the previously displayed url, and then the problem doesn't happen.
