I just recently upgraded from Adobe Photoshop CS3 to PS CS6. Everything wsa working fine until I trie to add a lighitng effect by going Filter, Render, Lighting Effects. It begins to load the effects and then stops part way through and just freezes up. I have to use the task manager just to close the program. Can anybody help me? Im running a 64-bit toshiba with 4 gigs of ram. Ive never had any problems like this with CS3.
