Is there a spherically mapped shader in tis particular file? I work in an ad agency and a co-worker of mine both run Carrara on Mac systems (both OS 9 and 10). We've found a bug in the program that automatically crashes Carrara when we try to re-open a file where there is a spherical map. Our only way around it is to open a new document in Carrara, import the old file, and change the offensive shader. Other than large file size, this is the only thing we've found that crashes the program.
