I've studied the relevant code and can see how I might improve this. The current code disowns the (primary) selection whenever the cursor moves before the highlighted selection, just in case it might be followed by operations that might alter the text under the selection. That's a simple rule of thumb, but overkill, since it doesn't mean that the selection actually changes. For example in the case I observed, the screen is updated in a region that did not overlap the selection.
If the primary selection is no longer available (because it was disowned), xterm falls back to cut buffers. But those are always ISO-8859-1, so some information is lost (and replaced by '#' characters). -- Thomas E. Dickey <[EMAIL PROTECTED]> http://invisible-island.net ftp://invisible-island.net
