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.
Microsoft -- because God hates us.
