We had our Xpression Studio updated to Version 4.1 Build 2134 back in December. We then upgraded to HD a couple months later, so I built a new graphics package using the updated software. Now, scenes will work fine, and then suddenly it will change an object completely black, almost as though it turned the object into a mask. Then only way to fix this is to completely replace the object. I'm just wondering if anyone has seen anything like this, and if there is anything I can do to fix the problem. Thanks.
