I've been having some weird issues when I try to edit. I'm unable to edit ways in Potlatch 2. It seems to be similar to the problems reported by 4267 on March 4.
For example, when I try to select a way, it lights up, but I am unable to add points. Also, after I do try to add a point, all ways no longer light up when I try to select them. 
In addition, when I first open OSM and click on "Edit," not all of the street data loads. Sometimes the name of a residential street is displayed, but the white line for the street is missing. Also, where there is a turning circle, sometimes only the dot for the turning circle is visible, but the white line for the short street leading to it is not visible.
I have tried to edit on two different computers and have gotten the same result. On one computer I recently installed a new version of Flash, but I'm not sure if the Flash update has been installed on the other computer. I use Firefox.
    This happened since the update to the interface that changed the look of the first page.
Anyone else experiencing this? Anyone know what's going on?
Thanks for your help.
