I am having issues with Photoshop CS4 on a users Lenovo Y550 laptop. It seems the software seems to lag or lockup when the user moves or modifies a layer. I have read many threads about openGL and such from Adobe helps sites but nothing has seemed to help me fix the issues. Does anyone have any ideas?<br />
