Maybe there is a special bug tracking website, but I don't want to go looking for that so I'm just telling my findings here.
First. The problem I had with mixed up audio is gone. So that's a big win for v8.67. Although I am a bit shocked by the amount of temp files videopad generates.
Now the issue I'm having with v8.67: Sometimes I can not pick op the bracket in the timeline to make a clip shorter. I's an intermittent problem, but a huge deal but annoying.
B.t.w. on a side note: the bracket a a bit small, hard to see and can not be picked up when the "playhead" is positioned in the same location.
