I use emacsclient (with Konsole tabs, if that matters). I usually have
several  emacsclient instances open in different tabs. When I start a clock
and then get away long enough, Emacs will prompt me to resolve the idle
time in different buffer that has the clock, usually in the first buffer
that I get back to. But often I cannot type a response in this buffer, or
in the original buffer's tab, so that I have to "killall emacsclient" and
reopen all the files/emacsclient instances.

Anyone experience the same?
