Gets hung up with error windows while starting up looking for README.TXT, LICENSE.TXT, and EBCDIC file…

It used to work, now, not so much…

The program works better then Telneting into the AS400 system but some basic features are missing. I had clients request a simple feature like- hold your hats now.. "Landscape Printing". They don't want all their prints (from Word or Excel etc..etc..) so using the system's print settings isn't the answer. I contacted the author and they outright told me they wouldn't be adding any such functionality. ..and they never did.. So they get kudos for updating and maintaining this application but a few hisses from the crowd for not implementing a simple landscape print option.

Shouldn't that be "Native TN5250 emulation for OSX"? It would be cool to run OSX on AS/400, but for some reason I don't see that forthcoming.
