Nico, it looks like you reposted old messages. It's one of those unfortunate things that happen pretty often when one writes offline (I do that too). This one looks new, though: > Does someone on the list know how X handles it buffer and if we can > access it easily ? There exist no X buffer. There is a protocol, and the X server acts only as communication media. One application claims ownership of the selection, and others can ask to retrieve the current "primary" selection (there more in addition to the primary one). It's not easy at all. A visible effect of the server handing messages and not holding data is that if you select text in an xterm that then exists, you won't be able to paste that text any more. /alessandro -- Alessandro Rubini, free software specialist.
