Re enable synchronious playback of multiple Videos

[Tomsun]

In the Version 2.x.x up to 2.2.8 it was possible to playback 2 videos simultaneously with one command bar, since version 3.0.0 this feature does not work anymore (in win 10 64 bit) as i tested with versions 3.0.0 3.0.7 and 3.0.8

The selection for multiple files to run snchron is still available, but it is only the first video visible. As there is no remark regarding that topic in the changelog for version 2.2.8 to 3.0.0, i assume this is only a glitch.

Could you please re-enable that feature, so i can use the actual versions in the future.

kind regards

Tom
