And ABC asked: Does Audacity suck? Well, I haven't stopped using it yet :)
If it makes unsolicited changes, then that would suck.
I haven't witnessed it personally, although I am NOT trying to discount your own experience.
I'll watch closely, and keep it on a very short leash in future. Thanks for the warning

You see me reassured. ;)

Well, the only thing I noticed that sucked is when you erase a bit of a track directly with the "delete" button on the keyboard, what provocates a "micro-nudge"... But once you know it it's easy to manage by choosing the "silence" or choose another "delete" option (sorry my version is French so I may lack of precision here).

For other kinds of change I haven't witnessed nothing, and tried to find about that on the net with no result. So that should be fine.

By the way, I use the last 1.3 Beta version, and it's far better than the previous one.
