> Could you please test this with the latest code to see if it's been resolved? It seems to work now. I wrote a small python script to test for it. The script is attached to this message, so that everybody else can try it out. This script writes a line of text with all possible combinations of foreground and background colours. It uses the ECMA-48 escape codes for changing colours. It also uses the ECMA-48 bold and blink display attributes to try to change the colours' intensity. To use this sciprt, run it and pipe the result to a pager. If you use less, use the -r option to allow less to print the escape sequences as raw strings. I could not get the blink attribute working on Linux console. Traditionally it changed the background colour to be bright, as the bold attribute does for the foreground colour. > Also, your "double cursor" problem should be resolved now. It's gone, thanks! -- Aura
