hi, (standard disclaimer: i'm a long time mac graphic designer / illustrator who has a surface pro 3)

when i open a single ptg file, i don't see a "close" menu like under the file commands, is this just an art rage thing?

when i open one ptg file, then go back to the desktop (in mac land, called the finder) and open up another file, it's as if a whole new version of the app launches, i see the start up art rage window. is this an art rage thing? if so, why do this, instead of just having all the ptg files open in the same area? when i quit the app, i have to quit it again for every different ptg file i had open.

thanks in advance for any help!
