ClearCase, hijack error and itimer signal

Hello Michael, from time to time I run into problem with ClearCase, e.g. when I try to hijack a file. I then get an error and the file is not updated (although it is hijacked). I have a debug for this: Debugger entered--Lisp error: (wrong-type-argument number-char-or-marker-p t) clearcase-utl-touch-file("D:\\ws\\Sources\\adc.c") clearcase-hijack("D:\\ws\\Sources\\adc.c") #<compiled-function nil "...(4)" [buffer-file-name clearcase-hijack] 2 ("c:\\Programme\\XEmacs\\xemacs-packages\\lisp\\clearcase\\clearcase.elc " . 26474) nil>() call-interactively(clearcase-hijack-current-buffer) recursive-edit() byte-code("..." [buffer-read-only noninteractive debugger-buffer middlestart debugger-args debugger-batch-max-lines pop-to-buffer debugger-mode debugger-setup-buffer count-lines 2 "...\n" message buffer-string kill-emacs debug backtrace-debug 3 t debugger-reenable "" nil recursive-edit standard-output] 3) After running in those problems I get regularly itimer error signals. Debug information for those is here: Debugger entered--Lisp error: (error "Selecting deleted or non-existent buffer") clearcase-post-update-check-process-buffer(#<killed buffer>) clearcase-utl-list-filter(clearcase-post-update-check-process-buffer (#<killed buffer>)) clearcase-post-update-timer-function() apply(clearcase-post-update-timer-function nil) byte-code("..."
