1. First of all, when I activate the layer, sometimes the problems are unclickable. No matter where I click and no matter what layers are on or off, it just won't select the problem. And then all of a sudden it works again (using Chrome on Win7).
2. And If I manage to click one, discarding problems because they are not actually problems doesn't work properly. An example is a 51 problem here. I checked it and the segments don't need to be connected, but no matter what option I select (mark as fixed/not a problem/other), as soon as I click resolved, the problem reappears.
