David, Tamar<br>
<br>
I have another issue. I'm using 'magit' (in emacs) to drive git. But it gives half-minute delays to do anything at all. There are lots of people complaining about it (googlable) but no solutions I can see. Do I have to give up magit?<br>
<br>
It used to be fine in earlier versions.<br>
<br>
Just at the moment it's Much Much More Serious. Even opening a file in emacs (nothing to do with git or (ostensibly) magit, takes nearly a minute!! In the process manager I can see lots of git activity -- just when I open a file in ordinary emacs!<br>
<br>
I have utterly no idea why this might be. I'm adding John Wiegley, my Emacs Friend<br>
<br>
Thanks<br>
<br>
Simon<br>
