Opening a similar file in hex mode made an amazing difference. The editor is very fast and responsive in this mode with rapid scrolling, easy movement around the file, and--- a critical test which many editors fail--- no delays in doing inserts in the middle of the file. I had one small issue; each byte inserted required a separate press of the 'insert' key to create a 00 byte which could then be edited. I also didn't have my window width wide enough to view everything but that's hardly XyScript's problem! With aloha from Hawai`i nei, -- Bob Newell Honolulu, Hawai`i - Via GNU-Linux/Emacs/Gnus/BBDB
