Hello Tracker users, version 6.3.2 is now ready and I recommend you upgrade before the Fall semester.

This version fixes two important bugs: (a) it no longer fails when marking a calibration stick with a mouse rather than automatically, and (b) the Xuggle video engine is again fully functional on Macs.

To upgrade, click the green "Now available" button on the toolbar and choose Upgrade Now. This will take you to the Tracker home page where you can download the full installer or upgrade installer for your platform. If you don't see the green button choose Help|Check For Upgrades. You can also download installers directly from ComPADRE at http://www.opensourcephysics.org/items/detail.cfm?ID=7365.

Cheers! Doug
