I can accept when the odd bits on a desktop background mess up in leopard, but it's when I use photoshop and final cut express when I have problems. The GUI message up where ever I'm dragging mouse or moving things best way to show it is these screen shots. http://www.filehive.com/files/0205/problem1.png http://www.filehive.com/files/0205/problem2.png Anyone else have this problem I can't find it anywhere and it's stopping me using final cut express, I can make it like clean refresh it away on photoshop by zooming but comes back again, terrible GUI glitch. I have already re-installed photoshop and final cut express and also archive and installed as I thought maybe the problem came from upgrading to leopard. Any help greatly appreciated.
