How long do you have to hold the mouse button down
for?
I see no effect after about 30 seconds then I got
bored...
Tried in outlook and wordpad. In fact the 'ambient'
CPU useage
actually appeared to flatten out.

The image is self explanatory...
--- [Description] ---
When you click to "any" close, maximize or
minimize
button's in windows Xp, [No matter whether it's IE
or
a WordPad] surprisingly there is 100% CPU use at
the
instant and it continues............ until you
release
the button! Moreover, we've noticed if you
continuously click the button for a long time [...
not
release it and hold ON ] we've seen gradual/slow
rise
in page-file use too...!!!
--- [Conclusion] ---
Hell... local DoS! That could be used by employees
working at different terminal..... (O;
