I’m having an odd issue in ZBrush 4, where the color box will stop updating after a while, though it will update if I mouseover.
I noticed when this happens, alpha preview has stopped working as well. Sometimes my layer labels won’t update either, IE: I’ll collapse a layer but it will still show till I mouseover and see that’s it’s gone.
I have an NVIDIA GTX 260 with the latest driver installed under Windows 7 64-bit.
