Thanks for the quick response, I believe I figured out the issue on my own (lots of time since I am working from home). First I may be wrong in some of my grammar that pertains to the programming environment, I am still learning. Correct me if I am wrong. I believe that in one of your booklets and some of your posts that the nodes (I am assuming this would be a screen) are independent and are not tied directly to anything. This is actually a rather nice feature, but with, I think with some caveats on usage. I had a main screen that opens, which is just a blue background, in essence its own node. The second screen drew a canvas with rounded corners (a second node). The second node has no knowledge of the first node. The canvas is basically a square or rectangle. The rounded corners are within this square of rectangle. When placed over the first node (blue background) the leftover space which I assumed would be transparent, became white. This I assume is because the second node has no knowledge of whats on the screen behind it and sometimes graphic transparency, is just white, if it has no knowledge of what to be transparent to..To fix this, I placed a pane behind the canvas. The pane having a background of blue with a canvas with rounded corners on top of it. Since the two where in the same node, the canvas had knowledge of the pane and the transparency worked. It worked this way, hopefully this is correct usage and not some quirk.
