sometimes it is not possible to copy /paste from web pgs, esp some popups. I have 1 in front of me that I really want to copy a bunch of text from. How do they do this? just some dumb HTML Kommand? is there a way around it?
Hard to tell without seeing it, as syzygyzys mentions you could copy the image with a graphics program (I typically use "snagit"), though it'll be saved as an image as opposed to text, so may not meet your needs. Another alternative, though not sure if it'll work in your scenario is to right click on the window and select "View Page Source" in Chrome, this may get you access to the text - once done, just search the page which is in html format for a keyword in the text your trying to copy.
Try doing it on this page and see if it works for you search for "headcase".
