And several new features including:

• Metal Window support (see the image above)
• Functions to convert HFS and POSIX file paths which will save a trip to appleScript
• Application function which returns the file path to the currently running copy of SuperCard or SuperCard Player.
• repeat for each
• volumeMount and volumeUnMount messages letting SC know when a volume is mounted or put away( pass the name of the volume)
