Hello mwoodj,

Thank you very much for such thoguhtful and delightful message.
We apologize for the issue. Could you let us know which edition and version of Astah you are using through all the different platform? (i.e. Astah Professional 6.6.3)

Also if possible, would you please provide us with the screen shots of the same diagram but on each platform so that we can compare the differences clearly? You can send us the images through e-mail.

Many thanks,
SJ
