Hi! I have a strange problem with painting in Photoshop. I tried to find a better description off this problem so I figured out the following : Open PhotoShop (in my case CS) File>New Settings Width 3000 pixels Height 30000 pixels Resolution 150 pixels/inch Color Mode: RGB Color 8 bit I choose for a black background Then I use an white brush and start brushing some lines, whatever comes up in my mind. Then I start smudging. After seconds I start to notice the waiting/busy icon from Windows. Is there by any change an solution for this problem? I also tried it on a Mac and the same thing happens (beach ball appears). Thanks in advance. Ronald
