What versions of WordPress and Geo Mashup are you using? 2.7.1 & 1.2.4

For problems, describe the problem and provide a URL where the problem is

Something bizarre is going on...

I have the plugin settings to display a connecting line for only a single 
category or mapped 
posts, but all of the sudden on this page I am seeing all sorts of lines that 
hadn't been there last 
time I checked.

I haven't upgraded WordPress or GeoMashup in a while.  Any idea why this is 
happening?
