I changed from B3D to BMax and I haven't looked back since.
IMHO MaxGUI is indeed poor for anything complex - I managed to create GUI functions in BMax that worked a lot better than a version in MaxGUI. Admittedly I was a beginner in MaxGUI, but I quickly realised that what I wanted just wasn't possible to do quickly or easily with it.
Here is a WIP ANSI style graphics package that was created using only standard BlitzMaz functions - http://www.iprice.remakes.org/stuff/MA.rar
I'm also working on a map editor that is based on the above code - http://www.iprice.remakes.org/stuff/MaxMapper.rar
