As we don't seem to use the same unzipper (IIRC, you trying with zipfiles, me with lzh ones), the problem must stand at another level. I wish very good luck to coders to find the bug!
Meaning something like me? Well, I downloaded arcview from the posted link, but I cannot get it extract anything using the unzip that's on my aranym. It just shows the content but when I drag it somewhere nothing happens (using teradesk). I have configured everything correct I think, but maybe I'm too stupid.
Why does arcview not know the command-syntax of the programs it uses by itself, why does the user have to enter them? I don't like it. Typical atari-coding.
