I tested with code similar to this:

            case VK_TAB:
                Tip from Jason 2010-08-05 regarding suppressing
Alt-TAB in the hook:


                For the computer user instead, using registry setting of
                [HKEY_CURRENT_USER\Control Panel\Desktop]


                //if (HasAltModifier(pkbdllhook->flags))
                if ((pkbdllhook->flags & LLKHF_ALTDOWN) != 0)
                    // return new IntPtr(1);
                    return TRUE;

It surprised me in several ways:

- It actually suppressed Alt-TAB, but for ALL RUNNING PROGRAMS! (That
make me think of that Eli once said that the low level keyboard hook
would affect all programs. It normally does not so there is something
strange here.)

So the code above can not be used in Emacs. Does someone has any idea
of what is wrong here?
