On 10th May Dennis Amith commented that he was getting a much faster opening of iM3 since he upgraded to OSX 10.2.6. I have to comment that I have not noticed any appreciable improvement since taking similar action, however the time it takes for iM3 to open in my setup is not unreasonable. I am using a G4-933 with 640 mb of RAM and a 20" Apple LCD. A little earlier Erica responded to a query from someone who was having performance problems as to whether they had tried the "minimize window" trick. From memory, she later commented that this was to do with exporting iMovie. Anyway, I decided to check whether the overall size of my iMovie3 window was minimized on my Desktop and it wasn't. Since grabbing the little tab in the bottom RH corner and dragging it as far as it will go towards the top LH corner the stability of the Application has improved tremendously. Previously, most times I tried to play around with audio in the Time Line, or "Save", the Appn. would crash. I hasten to add that I have not done a large amount of editing since making the adjustment and time will tell whether a lot of my performance problems have really gone away. A useful reminder and what Erica may have been referring to : ensure the "zoom" facility in the "Time Line" is minimized prior to exporting your movie; failure to do so could result in your audio being broken up. My $A two cents for what it is worth. Ian Tucker
