I use HTML Validator 0.7.9.5 on Firefox Debian-1.5.dfsg+1.5.0.7-2 (Testing). After some cleanup of unused libraries, I get the same trouble: HTML validator not able to run anymore.
After reinstalling libstdc++5, all works fine again. Hope it help. Jack.R -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
