I trying to use Render->View Image File... to view an image but after selecting it in the file dialouge nothing shows up. I can't use the Grab Viewport feature either, the image doesn't show up. I can open the Rendered Frame Window (VBF) but nothing happens if I click on the Clone Rendered Frame Window button. I'm using Max 2013 64bit with the new PU06, but I'm having similar issues in Max 2012.
Does anyone know how to fix this? Is there a way to open the Image Viewer through script that I can try?
Cheers!
