Thanks, will tidy up the code and turn off the filter side of things and see if that makes a difference and will sort out something to post up the zip here on this thread rather than as a proper addon. It's only a test addon at the moment that will ultimately go into the gatherer addon once it's up and running.

I'm glad that you can't see anything wrong functionally as it means I at least had the idea right, just that somewhere something is going wrong, probably something silly that doesn't cause an error like my infamous = instead of == rofl. But that was the first thing I checked.

edit: Okay, tidied up code, fixed a couple of visual glitches .. here's the code in its entirety.

Everything seems to work except the drawing of the pin itself. Probably something so simple we'll kick ourselves. Me especially.
