I've been watching Elvis' PI Apprentice Guide CD and today found the Project Files. I double clicked on a file and, as it should, PI was launched and the file opened. If I double click on another project file i get a message asking if I want to save the existing file (to which I replied, "No"). The next file loads, but when I press the "Play" button, the program crashes.
If I open PI and just load the project files directly there is no problem...only if I double click the project file outside PI to get it to load.
Using a MACBOOK Pro (latest 17" w/ NVidia 9400 Graphics card. 4GB Ram.
Not a terrible problem...maybe you're aware of it...or I have a setting wrong somewhere?
