I'm not sure if this is a bug or not, or if it's just not included yet, but I can't seem to associate stackz files with stackz 07. I'm running vista. I right click a .szm file, 'open with', 'choose default program', click browse and browse to stackz 07 RC5 exe file. It doesn't add it to the program list however, and will not associate correctly. Is this just because you don't want it overwriting stackz 06 associations? If this is not a bug, when can we expect to see the file associations working?
