genorb:It looks silly as a solution but it really make a difference. If I play with the default theme (with aero, transparent windows etc), I cannot ding at all (even if the meter is smooth). The meter always stops a tad later after I click and I miss late. But if I change the theme (I use windows classic, similar to XP), it works as expected.
Exactly Gen gen,On some machines Windows 7 Aero especially on the transparency theme will have a delay on click,you need to trim the Aero look as much as possible even go to control panel and Adjust for best performance,
