> Hello All,
>
> I would like to use menu command:
> ImageJ>Hide ImageJ
> (on the Mac) to perform longish image processing invisibly, and avoid that
> clicking accidentally into an image, or pressing a key that switches to a
> different hyperstack channel, disturbs the macro operation.
>
> However, whenever ImageJ opens a new window (see macro), it returns to
> visibility.
> The current behaviour appears not logical to me. I only could work-around
> by setting everything into batch mode (not practical) or to switch to a
> different "Space" (not practical either).
> Ideally, after processing I would tell ImageJ to return to visibility and
> show "Processing finished".
