Re: [STUMP] Stump, Emacs and X selection.

[David Bjergaard]

Hi Dimitri,

I'm not sure why you have to run it twice.  I tried the snippet, and I didn't
see the text pop up until the second time I wrote it.  As for dropping non-latin
characters: this is a known issue with StumpWM, and one that I'm slowly trying
to address.

If you can get the bugs worked out (or not) you should put this on the wiki
since its a great example of using stumpwm to automate window actions that may
be tedious.
