Extreme Noob here, but I seem to be having some type of issue with containers. Whenever I contain numerous graphics with embedded alpha channels, it does not seem to translate the alpha information in the final container. In the end, I am left with a container with a black background with no transparency available.
Is there a button or something I'm not turning on? Just starting to get my feet wet with this program, but I know for certain that I was not having this problem before the Extension 1 upgrade.
