If your using the Shockwave 11.3.31.331 that is the wrong one. That one has the Pepper Flash Player that is causing the meter to jump. Disable that and use the Shockwave Adobe Flash version 11,4,402,278 which is the newest one and works perfectly fine in Chrome.
Or as Courtney mentioned use a different Browser as Chrome is going to keep updating and re-enabling the crappy one.
