Hi all!. I have a late 2009 MacBook with the stock (2Gb) ram and 250Gb hdd etc... but I don't see the relevance of this, although I thought it better to include specs anyhow. I have lost an hours worth of work, TWICE today, due to Premiere Pro CS5 deciding to beachball on me, even when my autosave period is set to 2 mins . Is this a widespread issue? I have the very latest Snow Leopard & CS5 updates, but it seems to happen when I am doing motion keyframing; specifically when I am moving the position of a large still image between two keyframe points. So much for autosave - it saved NOTHING - I just end up with an empty project. Am I missing something here, or being incredibly stupid?... Thanks guys - hope someone can shed some light on this.
