I'm using lucid.

It works for me.

    (The Alt-PrintScreen choice is a bit unfortunate.  This is also known as
    SysRq.  The kernel has a bunch of magic keyboard commands you can invoke
    by holding down Alt+SysRq+letter, e.g. Alt+SysRq+s writes dirty cache
    pages back to disk.  However when you hold down Alt+SysRq while
    searching for the s, GNOME starts taking screenshots of the current
    window -- I end up with 10--15 of "save screenshot" dialogs that I
    have to close one-by-one.)

If it didn't pop up a dialog showing a thumbnail of the screenshot and
asking where to save it, this means it crashed.  I can reproduce:

    $ gnome-screenshot --interactive

(select "Current window", hit Enter)

    The program 'gnome-screenshot' received an X Window System error.
    This probably reflects a bug in the program.
    The error was 'BadWindow (invalid Window parameter)'.
      (Details: serial 4255 error_code 3 request_code 15 minor_code 0)
      (Note to programmers: normally, X errors are reported asynchronously;
       that is, you will receive the error a while after causing it.
       To debug your program, run it with the --sync command line
       option to change this behavior. You can then get a meaningful
       backtrace from your debugger if you break on the gdk_x_error() function.)

Use GIMP for taking screenshots: File -> Create -> Screenshot...
Or some other tool.
