For simple files, the 3d widget appears when I convert an object to a Postcard and responds to my use of it. For some of my complex multi-layer files, the widget shows up but does not respond to my mouse clicks. It just sits there. I can manipulate the object using the 3d navigation tools, but the widget is useless. Is this a memory problem? I'm having problems with a 170 MB file with no other apps running other than Photoshop.
I'm on a Mac 2.66 GHz PowerBook with 8GB of RAM running OSX 10.8.5.
