When I try to mute out small parts, eg. speaking of words, in the audio of a clip, it works sometimes and sometimes not. I usually have to reset the envelope, and then at last it works. If I cut a clip in two, the envelope is changed, like eg. fading from 0 to full, but somehow still keeping my mute outs, though I cannot see them anymore.
That glitch is really ont thing that kept me from choosing AVS in the first place as editor amongst many others. But now I have chosen to go withe AVS, because I hope it is a but that will be fixed in a future version.
I run Windows 7, and of course, I have the latest AVS versions installed.
