I have been happy in v 6.7.

I accidentally opened a stack in v8, and now it will not open in 6.7. "...Created in a new version" is what I get. I did not save it in v8, it just opened it.

Can I get it back to 6.7"

EDIT: Reconstituted by cutting and pasting scripts from v8 stack back to a slightly older v6 stack, so no big deal. What I learned (again) was that if v8 is on my machine, it will open when an ostensible v6 stack is double-clicked in the finder. Must be careful about that, even though I think I caught myself and am sure I did not save in v8. So just opening that way made it a v8 stack? I now store that version in the trash, where it cannot sneak up on me.

But still want to know if there is a legacy reversion method.

File -> Save As includes an option to save a stack file in any previous version going back more than a decade.

Even better: once chosen is stays with the stack, so if you open it in v7 or v8 later the save routines in those versions will save it in the format you'd selected previously.

Hi Craig and Richard,

this is broken in dp-14/15 that doesn't respect the pref setting "preserve stackfileversion".
LC8-dp15 changes always from <= REV550 to REV700, at least on Mac.

Already reported as bug some weeks/days ago (#16955 and #16992), will be resolved in dp-16.

I use currently the road:
Open with LC 7 and Save as ... (NEW name, don't overwrite, and set legacy version 5.5).

Thanks Richard and Hermann.

Very good of the team to provide this flexibility.
