It seems, that under 7b2 the encryption is somehow buggy. What I did was password protect and pack some files with 6.56 and then added some files with 7b. The files added later with 7b do not get encrypted, so when I open a file added with 7b2 within the zip, it does not ask for password, other files do.
On more playing around I found, that files packed with 6.56 always protect the zip, while 7b2 never does. Did anyone else found this?
On similar matter. Is it possible to also prevent opening the list of files in password protected files?
