Icons missing (as in the picture). In Windows 10 Pro (1709 OS Build 16299.192).
Another thing, if it is relevant. When I first installed this beta 3 version and try to open a v.1 .scrivx , I had to end the task in the task manager because Scrivener froze trying to convert it. So I create a new project, closed it and tried the conversion again, this time successful.
