And a note from SVS about a particular bug he fixed: "This was a screen with the message "Operation/Error Press Return" when the WP goes into internal error. The problem was that the text was displayed yellow, while the background was *white*, then the page resulted non-readable. (The rest of the page showed other messages / monitor data (?)...) In the fixed version of WP I set as background color a neutral gray, so the texts are readable when both colors are used (yellow [standard], or cyan [CO command on]). Hoping this will be appreciate by the users that have errors using 3+1; to fix it took me many time... :)"
