Like the title says, I'm starting with a preset on an audio effect, and it turns out that every tweak I do it overwrites the old preset. So if I don't like what I'm doing and I want to go back to the original preset to start tweaking over again from that point, well too bad because it's been overwritten with my tweaks. This happens when tweaking my own presets, or using the default presets that come with the plugins, and is true for the built in Vegas plugins, as well as third party VST plugins. This didn't used to be the case in older versions of Vegas, but I've noticed it in 14 for a long time, and I've finally gotten frustrated enough to ask. What can I do to prevent this strange behaviour which really should not be the default behaviour, and didn't used to be.
