Then Apple released HyperCard and that was nice, until they dropped it.
Then Runtime Revolution was released, and I found it quite nice to use, then they opensourced it as Livecode and I pledged for that, then they quit supporting the Community Edition and closed the code again (anyone know if anyone is making progress on getting this to compile/work/install?).
These days I just use Python, but I'd really like to see a nice option for GUI development.
