Chris the symbol window will not display properly if the classicladder user program is loaded twice-as was the normal way to load it before. I think this is because of the temp file that classicladder uses get re-initialised and for whatever reason the symbols window does not get updated and that is why when you make changes to the ladder program u can have problems saving it. I have not figured out exactly what's going on but it is on my to do list. I like the idea that you can load the classicladder GUI from AXIS -it should be this way. There must be away for the hal user program to monitor it's realtime program to tell if it's closed or not- then the user program could clear out the temp file etc when the classicladder_rt shuts down and you could have a hal pin to open the GUI.-Just some ideas
Thanks I'm glad that other people find it useful!
