I have the exact same problem with ‘Run’ not working until I’ve run a sample file, then the Terminal isn’t clearing, and continues to display the ‘old’ variables**, and not outputing to the Terminal window.
There also seems to be a mix of conflicting information in the Help files, tutorials, PDF files and on the web pages.
Part of my problem is when lines like these are included…
vp : "Conduit", or
vp : "ViewPort Configuration", or
These three OBJ are from various library files but I can’t use them in my source code like they are in the samples. These all need to be given different nicknames, such as vpConfig, vpTerm and vpConduit.
** These old variables don’t clear even when ViewPort is closed down, then restarted with only MY program.
