Hugh,
Do you think you will ever find time to update GCGB to support the latest GCB release?
I really like a lot of the GUI features such as easy setup of the LCD pins or 7 seg pins.
And having the ability to type in text and then show it in flow chart makes the GCGB screen a great IDE for GCB.
Also it makes it easier to teach kids the basics with Graphical programming and then when they are ready they can easily see how to create the same program in text mode.
And the ability to see the assembly code in one click is so handy for the experienced user.

I really think GCGB is a great tool but it doesn't appear to be updated in a long time.
