I just noticed tonight that the Media Browser window constantly flashes about twice a minute with random intervals; however, it hasn't done so for a few minutes. Anyone have any idea why this is happening? If it matters, the video folder of the current project is open inside Media Browser and its XDCAM EX footage, and it is an Areca 1680ix with 6 2TB Seagate Constellation ES drives in Raid 5. All drives are still alive otherwise the dang Areca card would be beeping LOUDLY.
