I just started using VW 2013 DEMO on a new iMac (OSX 10.8) and I created a new workspace. Since that time, I cannot further edit this workspace.
Firstly, upon selecting EDIT, I am told that I have no access and to check the file and directory permissions. I have done this to no avail. Secondly, if I attempt to create a COPY of the custom workspace, I am told that the file is either invalid or I do not have enough memory.
The palettes are not accessible, so maybe the file is invalid. I spent a great deal of time on this and prefer not to have to do it again.
VW 2013 has many of the same problems as previous versions.... I find the lack of attention to the GUI is a distinctly overlooked tendency of this perpetually 'almost' great software. Been using VW for two decades so I am clearly devoted.
The machine has 4MB of RAM.
