"Autosave should be deferred so that it only happens when maya is idle. I've encountered several UI bugs because of this. The biggest believe is related it autosaving while the scrub tool is active, the UI no longer refreshes and maya must be restarted. I've encountered several other issues like it jumping out of tools I'm using or the selection tool stops working. Please use something like the evalDeferred() mel command for autosave."
