Hi, My scenario is a little different than what you have described. I don't have images on buttons. I have my custom window (which is a black colored image) and on it are the static texts. These texts are displaying blurred. Although i have not been able to figure out why is this happening, but i got a work around by using a different color shade of window image. So my problem is solved, but if anyone could explain the reason for that, it would be nice. It would come in handy for future use.
