LiveCode won't recognize my stack

I have two monitors as well. And I use a key combination and a plug-in to
reset the loc of the very stacks you mentioned, plus the SE. These change
each time I save a stack. 

The point being that I never have a problem saving, only that I have to
reset the loc of the topStack and the others each time I do.

More than worth it to have two monitors, though.

Nothing has changed here in any recent version.

This is most likely because you haven't got the stackFiles property set 
up, or the defaultFolder is not what you are expecting it to be - i.e. 
the engine cannot find the stack with filename "LicenseKey.IW" relative 
to the current folder.

The IDE still uses the form of 'answer file' which specifies a 
creator/filetype and an extension. I suspect either one of:

  A) the creator/filetype is actually recognised by more recent versions 
of macOS (i.e. they are ignored completely - I don't recall a report 
against Mojave, but it is entirely possible Catalina no longer supports 

  B) The file has just lost its creator/filetype and thus is being 
filtered out (this can happen if a file is archived via a format which 
doesn't support these attributes, or has transmitted through an FS which

Use All Files and select it that way, as you have been doing :)
