Color markers on the wheel or triangular on the lines, as well as cursors on uploaded images (even on the default image) would not move. I can select different themes, moods, and rules, all links work properly. Please, help.
In case somebody else has this issue, I figured it out. It doesn't work in Firefox for Mac OS, but works just right in Safari.
I was able to reproduce the behavior on my Mac as well, (tested in Firefox 3.6.25) and like you, it did work okay in Safari. Thanks for calling this out, I'll report the issue to the product team.
