Well, I don't know WHAT to think now !!
I didn't use Galaxy to download/install Asylum
specifically because a couple of weeks ago I got a message from GOG telling me that my Galaxy was out of date.
But it seemed such a rigmarole at the time to update it that I just left it for then.
So when I eventually downloaded/installed Asylum, I just used the game files (as I have said) which is what I tend to do most of the time
anyway.
However .... I looked at Galaxy today and Asylum was showing as "installed" ....
and the "Play" button was operative.
So I clicked on it - and the game launched !!!!
How is that possible ??
And it opened at that same spot I had exited from my in initial "look-see" after checking if making a save worked.
AND I could carry on playing

Any ideas ????
