I am having a small problem with the preset browser. If I apply any effect and go to the preset browser the thumbnail windows are black. You can see the example effects are being applied however.
I have made sure that preview over source is selected not preview over black.
If I then apply a 2nd effect, usually this will display correctly and the first effect will also now display. Sometimes it takes the application of a third effect to kick the browser into life but more often than not 2 will do the trick.
It does not seem to matter which effects I use.
I have Sapphire version 6.12 FCP V7.03 OS 10.7.5 on a i7 Macbook Pro non retina high res non glossy screen model. Which has the Nvidia GT650M graphics card with 1Gig video ram.
The plug-ins themselves all work totally fine, it is limited to the preview window.
