Bug Description

I think it would be better to inactive the buttons when they don't have any sens.
For example:
- Stop button should not be active when you don't perform a scan action (maybe it should only appear during scanning, with a sort of progress bar?)
- Save, print, send by email, rotate and crop should not be available before a document has been scanned.

More generally, I am not convinced by the fact to have all the buttons in a menu, because it doesn't represent very well the chaining between actions, which are:
- select scan options (color, resolution)
- perform a preview and select scan area (eventually)
- scan
- post-scan actions (rotate or crop)
- final actions (print, email or save)

Agree stop button should only be active during scanning.

Don't agree about limiting the other options:
- You can save at any time because there is always a document present (it is a blank page by default).
- You can rotate and set area at any time as there is no reason to make the user wait to perform this - a use case would be a user scanning a document and realising as it scans it's upside down.

The order of actions I see users performing are:
- Scanning the document
- Printing, emailing or saving it

Optional actions:
- Changing to text mode
- Rotating (I expect this only has to be performed once, for the next scan the rotation will probably be correct)
- Set area (only if you need to - for a lot of full page documents this is not necessarily required)
- Re-scanning if it needs it (I'm not convinced preview is necessary - do you preview with your digital camera?)

Thanks for your answer Robert.
So about the stop button, what do you think about remove it from the buttons bar and add it to a progress windows which would appears during scanning? It would be the most logical in my opinion.

No dialogs. A dialog would cover the image being scanned, the progress is already shown on the scanned page. There is already a strong convention for having a stop button in toolbars (e.g. web-browsers).

So I understand that the only work which can be done under that bug is inactivate the stop button when there is no scanning in progress.
I am right?

Yes, as that is the only action that is active when it has no action.
