@rinigus, outside of the current hunting of the snark... err, I mean, the hanging bug, I have to report one more thing ;(

First of all HUGE thanks for the POI management. It was a feature badly missing in WhoGo and early versions of Pure. But it may still need some attention. When I selected "Clear map" from the menu this morning, it wiped all my laboriously added POIs. That might be as intended but it was not as expected. I would expect "Clear map" to clear any marks you've made on the map but to keep POIs alone.

Another option might be to remove the "Clear map" option altogether, if the only marks on the map are POIs anyway, and/or move it to the POI management page.
