Alpha image issues in Light Box

Since ZBrush 4 R2, I got a problem in Light Box about Alpha images. Light Box displays some images as just Black.
On Zbrush4, there is no problem. Anyone knows this issues?
Image files are PSD that have 16bit Gray color, no layer, no alpha channel in Photoshop CS5.
Here is Capture image of my Zbrush4 R2. It shows some images just Black.:cry:

R2 seems to have issues with 16 bit image import at present.

Thanks you!!!
I changed alpha images to 8 bit Gray scale. They works fine!!!:smiley:
