Hi there. I've noticed that when i have finder open in a folder with several movie files in it, the window begins to behave strangely. Basically, it keeps dropping in and out of focus really quickly, switching every half a second or so. It makes clicking on files VERY tedious. Anyone else with this? Running 10.5.4 at the moment... and from what I can tell this might be Quick Look related, as the Quick Look server jumps up in CPU cycles when this happens.. but it may be normal, I am not sure... Oh and tried repairing permissions already!
