so iv searched the forums for a bit and didn't find anything, so i thought i might ask. i was wondering how to print screen or screen shot on backtrack the key on the keyboard didn't work, well i don't think it did, anyways, i pressed the button then when into kolourpaint and tried to paste but there was nothing to paste, any help would be good thanks

iv also searched the forum on how to change the background, i have located the files, and changed the image and kept the original file names but it still loads the normal standard image, thank you for your help in advance!
