Recently purchased the latest Art Rage 6 and have played around with the latest version. I ran into a problem I cannot figure out a solution to, only a work around.

I applied and tried different default media brushes in a landscape painting. Had different objects painted on several different layers and then merged the layers down to a one layer image. When continuing on this single mergd layer I ran into a problem of not being able to paint anything over certain areas of the image. This only occurred in certain areas of the image. I did however discover that the eraser worked and then was able to paint into the area. I would conclude there are certain medias in this program that produce that result? Not quite sure which one it would be since I do not remember what media I used for the areas in question that created this problem and/or effect. If no media in this program is suppose to create this effect then maybe there is a flaw here?
