if iCal comes close for you try NOW Software’s Up To Date (www.nowsoftware.com) we use it and it works great for us. Cross platform / syncable with a server / very easy to use, but powerful
Were you ever able to work this out ? and if so how ?
I have run into the same problem, moved the Kona SD card to slot 3 (from slot 4) and still have same trouble (this G5 has 8 RAM slots so it doesn’t seem to be the other problem mentioned)
Another great filter for this problem is Sapphire’s Clamp Chroma under their Adjust Filters. A true clamp for both Chroma and Luma levels without lowering overall values. Perhaps an expensive route to solve just this one problem, but the rest of their effects are great.
