Refresh only after key pressed

Refresh only after key pressed

[Torsten Bronger]

Hallöchen!

I sometimes observe that the window is not refreshed before I press
any key.  The display "hangs".  For example, I start Gnus, but still
see my opened file (for way too long).  I press a cursor key, and
suddenly see my Gnus groups.

This is difficult to reproduce.  Emacs just seems to be in this
"mode of operation" sometimes.

Does anybody know the cause of this?

Tschö,
Torsten.

If "my opened file" is current buffer right before you
invoked Gnus, then actually it does happen that Gnus
takes a while to start.

Did you do this?

    (setq gnus-inhibit-startup-message t)

If you did, depending on how much Gnus you do (Usenet,
Gmane, mail, RSS ...) it can take a while if there is
a lot to be fetched.

If you didn't inhibit the Gnus gnu, then when you
start Gnus the gnu should appear instantly and only
after that should there be the fetch pause.

OK, that shouldn't happen. Perhaps your keystroke
coincides with the completion of `gnus'?

What happens if you don't press a cursor key - will it
be forever un-refreshed?

(It is bad karma to use the cursor keys btw.)

No, it shouldn't be like that.

Gnus is only an example.  Automatic reverting of buffers of
externally changed files is another.

Yes.  Well, at least for a ridiculously long time.

Tschö,
Torsten.

So you do that "automatically" and the result is Emacs
hangs until you press a cursor key?

I think I'll stick to manual, thank you :)
