i use yet higgui, mich more stable and faster and faster to code...
HighGUI's good, but my issue with it (and indeed, every other GUI I'd used) was that they were all still based on a system of windows. It just didn't suit what I was after. I tried writing a wrapper for it that would encase it in a panel system but with the amount of work involved, I realised I'd be better writing my own.
Anyhow, the stability issues will get ironed out. I'm aware of quite a few problems here and there but if you can point more out, that'd be great. Don't want to miss anything!
