I can confirm, that Axe-Edit has occasionally some problems, when moving presets.
I.e when I move a preset to another free place and after that move another (second) preset to the place,
where the the first one has been removed.
Then often the AxeFx himself hangs, Out 1 Clip & Out 2 Clip led's are shining constantly
and a loud very high tone (like feedback) comes out of the AxeFx output.
Very bad for my ears and my headphones.
Meanwhile I'm working in the preset manager only with muted output volumes!
