We have just encountered a user running OSX Mountain Lion where the toolbox was missing scroll bars and does not resize, which basically makes it impossible use more than a few items. The issue was present in Safari, Firefox and Chrome - all of them the latest version.
Does this sound familiar to any out there?
What toolbox are you refering to? I just tried on the demo.episerver.com site and both the right click menu and toolboxes over the xhtml strings show up as one would expect.
What version of EPi are you trying it on?
I am referring to the toolbox containing the composer functions, composer templates etc. The site is running on EPi 6 R2 and Composer 4.
Hmm. Tried Composer as well and had no problem.
Tried clearing the cache for the browsers?
Has the site been upgraded?
Does demo.episerver.com work for you?
