CN language version's motion tracking progress hang at 0% unless minimize the Vegas Pro window.
Not only motion tracking but also other progress window like motion tracker, such as stabilization.
And the cancel button can function if click it.
The package I tested was from http://dl05.magix.net//2019/VEGASPro17/Update/VEGAS_Pro_17.0.0.321_CN.exe
This is not a universal language version but I wish vegas team can see it.
