Since upgrading to X4 (w/ sp1), I am having LOTS of trouble trimming and / or combining objects. Here is an example from today. I have an image that is essentially a mirror right to left of itself. It is CLEAN of goofy points and should combine perfectly, however as you can see in the third picture, when I combine all of the objects half of them disappear! They are still present in the wireframe, they just don't fill correctly as a combined object. I have never had this problem in any of the other versions of Corel, and I've been using it religiously since 7. Also, the gradient fills are all goofed up, but that is a topic for another post. Any suggestions?
