Once again I cannot comment on a response to my previous post. When I press the comment button nothing happens. This is very frustrating as I don't have time to muck around just trying to get a question answered!
In response to the last comment from Daisuke Okuda I have this issue with all process boxes whether I create a brand new one or try to change an existing one. I am using the default font (I do not change it). What this font actually is is not shown in BizAgi. I was trying to attach a screenshot of this but this forum is also not letting me attach files at the moment (it is jpg which seems to match your file criteria). I must say nothing seems simple with BizAgi!
