Hi All, Tedd tells me that when making the FB Carbon Editor the default for FB files, the default app becomes TheWindowMaker and not FutureBasic (Carbon). This sounds really sensible to me but I don't think it's what most of us want :) I registered TWM's creator code (TWMk) with Apple a while back and that's what appears in my BNDL rsrc. I suspect it's something to do with those 'plst' thingies but I ain't got the knowledge. [Hey! RC, where's that plst editor you promised us?] I don't have the FB Carbon Editor so I can't check it out. Any ideas how I can fix this? Bernie
