So many problems with photoshop CS5.1. CTRL+Z doesn't undo more that one step. CTR+Mouse Scroll doesn't zoom. Clicking on a different layer in the image doesn't select that layer. Selecting text is impossible. Things are displayed off the screen on a netbook PC. Takes forever to install, load and takes up hundreds of megabytes of HDD space. Screw photoshop and its bullshit problems. I have had enough. So I changed to GIMP. GIMP - GNU IMAGE MANIPULATION PROGRAM - https://www.gimp.org/ Open Source Free Software Opens Photoshop Files Fixes all of Photoshops stupid bullshit problems listed above and yeah it's free!
