Undo is basically unusable because there are constant Set Stream Flags showing up in my After Effects history. Running the latest version of AE CS6. I'm working with RED .R3D files imported from Premiere Pro using "Replace with After Effects Composition." Both AE and PPro have the latest RED importer files installed. Any ideas? Searched around but couldn't find a solution... seems like whatever Set Stream Flags is, it's being activated automatically and shouldn't show up in the Undo history. Thanks!
