That is weird. Unfortunately I don't have a 64bit OS to test it. Processing JS is just a parser that parses processing (java) code and runs it as JS. I tried to write everything in JS but its major pain in the butt, since js has very weird way of doing classes (they are not even called classes). H

Looking real good. I like the red edges prior to deletion when you drag outside the canvas. I've now run this on two machines - one is 32-bit, one 64-bit. Otherwise pretty much the same - recent Firefox on KUbuntu, approx 3GHz chips. The editor is very crisp and robust on the 32-bit machine. O

Yeah, it was supposed to be a feature, but I agree that double click to remove is easier and less error-prone. I will give it a few days to see if anybody has good argument why we should keep it and if not I will remove it. I will also make undo for the last erased vertex. Rado On May 5, 9:13 a
