Gotcha :)

I have to say, it was an interesting read to go through. I get that they were testing it as an aid to new users, to enable them to more fully follow the tutorial without distractions, and I could see that if the backdrop didn't completely cover the rest of your desktop. For instance, if the backdrop only covered the area directly behind the Lc working palettes, *that* might create the 'unified' look he was referring to.

Heck, if it only covered that area, I might use it myself :)

Hm. I wonder how hard that would be to figure out :roll:

Thanks for the link, I think I had read that.
What is interesting is that on reset preferences the backdrop colour is set to white, but on opening Livecode again the backdrop is grey.
My workaround is to put this in the project's preOpenStack handler

if licensed() then # Returns true if the development environment is running.
set the backdrop to none
end if
Then open live code by double clicking my project file.
However it is frustrating. It happened when I
Deleted all versions of Livecode using CleanMyMac
Installed the latest livecode 9
Then after I had a play. Deleted that version then installed a fresh version of 8.1.7 rc1
How can I make my background choice in preferences stick?

Interesting. That didn't work for me, but the following did:
.. launch LC9
.. get a completely gray screen
.. alt-tab my way to LiveCode
.. now the menubar and other palettes are in front of the backdrop
.. disable the backdrop to set the preference

so everything's there, it's just that the backdrop is in front of all other windows and it's not passing (keyboard) events through.

What I take this to mean is that if you have an earlier version which set preferences installed (not sure which vers. prefs 9 might also use? 7x? 8x? ) where you had turned off the backdrop, then installed 9 that has the problem, the issue doesn't present itself.

So in that one thread there were actually 2 ways to try to work around it. Since your telling us Mark's didn't solve it (setting it in 9's prefs), perhaps just removing everything one more time, including the prefs files, then installing an older working version, setting the pref, (making sure backdrop off seting works), and installing 9 after that will ?

Sounds like a right pita, but I am sure we've all seen or dealt with worse, I know I have.

It might be easier than that. Install an older version, launch it, toggle the backdrop a couple of times to set the preferences up. Quit. Launch LC 9 and it should honor the setting.

LC 8 and 9 share the same prefs file. Next time you clean up the Mac, don't delete it.
