have PS cc and when I use Lighting effects a lighting effects window pops up but it won't show me light handles or a widget to move the lights around. i can switch lights to adjust their properties but can't move the lights around my image, So it is of little or no use without that functionality.
Can any one help me solve this problem? ..................... Windows 7os, nvidia geforce 650 with latest drivers updated.
Try disabling the OpenGL support in Preferneces > Performance. You'll need to reopen the image for this change to go into effect.
