There should be no iconfied Completions frame in the test I gave you.

The problem arises only when the Completions frame is newly _created_, as I
tried to explain.  If you use `M-x f TAB o' (recipe) after the frame has already
been created then the input focus is not a problem.

If you have the frame already, then please delete it and try `M-x f TAB o'
again.

As I said, it's possible that this is Windows-specific.  Windows is I think
(thought) a bit peculiar when it comes to its auto-selecting a new frame -  but
you said that most window mgrs do that now.  I still wonder if this isn't
Windows-specific, since you cannot reproduce it and it is systematic for me when
I follow the same recipe.

Do you mean my .el or .el from Emacs sources?  In the files I provided for the
test, please use only .el, no .elc.

I'll certainly do that.

But what about that `display-buffer' call in
`icicle-display-candidates-in-Completions'?  Can you suggest a change for it?
Does that code look like it _should_ work after your changes, or should it be
changed?

And you mentioned the `save-selected-window' around that `display-buffer' call.
Does that need to be changed somehow?
