AH HA! I spent a little more time in the past few minutes looking over the dillorc file to see if there's something I aimlessly missed option wise. Turns out I seem to have found the issue! This is what I had: # Mouse middle click by default drives drag-scrolling. # To paste an URL into the window instead of scrolling, set it to NO. # Note: You could always paste the URL onto the URL box clear button. middle_click_drags_page=NO I now changed it to: #middle_click_drags_page=NO Reran Dillo and I can now copy/paste into Dillo's web page forms without the output from the copy buffer always going into the Dillo url entry box! If this is the expected behavior of copy/paste when this option is set to "NO", then I'd suggest putting in a warning into the comment area of the dillorc that it will conflict with copy/paste operations when using the mouse middle button. Cheers!
