Err, there is a progress bar that shows Analysis is working...
Anyhow, Analysis is not multi-threaded, so once a slow function like the
copying of peaks is processing you have to wait.
The Cancel Cloning button is just a means of backing out before you
choose a target list. I can reset this button before the cloning function
begins for real, if it is causing confusion.

It does not happen in the background.
Analysis can do nothing else in the mean time (although I suspect that
Tkinter will still record some mouse events).

I think this dialog occurs at the wrong time. I will move it to after
selection of the destination.

This is correct. It is a chance to back out...

This is why there is the Cancel Cloning button!
If you select the wrong list then that's you fault, but every opportunity
is given to stop the process until the last moment.
I seriously don't want to add the ability to stop things part way through.
To go back into the graphics loop will slow things down even more. Also it
is more work for little gain.

I am happy to make changes to disable the Cancel Cloning button earlier and
change the order of dialogs. I think this will make things clearer, but I
don't really see that it needs more than that.

Commenting about how much hardship Analysis has caused isn't especially
helpful. If anything, it makes us less inclined to help.
Also we can't always reply to all e-mails immediately, even if you are
stuck or in a hurry.
