I have both AC16 and AC15 on my computer and use AC16 mostly. Why doesn't Archicad remember the version last used for the project that I am opening? Time and again a current AC16 project tries to open in AC15 - it won't, of course. And that happens even when I haven't used AC15 for quite some time (unless opening incorrectly is counted). Gggrrr!
