CVS: Prob with Clipboard

Hi! "XEmacs 21.2 (beta34) \"Molpe\" [Lucid] (i386-unknown-freebsd3.5) of Fri Jul 14 2000 on lamia.LF.net" Whenever I mark a text and try to re-insert it, I get the following error: Signaling: (selection-conversion-error "selection owner couldn't convert" CLIPBOARD STRING) get-selection-internal(CLIPBOARD STRING) get-selection(CLIPBOARD) get-clipboard() current-kill(0) yank(nil) call-interactively(yank) After this, I can't kill buffers, or the application, gnus also stalls. Any hints? Thanks, norbert.
