fighting still with the slowness in Org as soon as the mouse "hits" some lines 
in agenda view or even in any org file
I thought why not run the "fast displaying" emacs under Linux and redirect the 
display to my windows X-server.
Well - the X-server under Windows (X-Deep 4.6.5) slows the display of refreshes 
even more.
So this is of no help - at least with my X-Server.

Can't I control the creation of links in agenda view?
I did not find a variable to configure.

OK, a little later I found this

(setq mouse-highlight nil)

That does what I need, the awful timeout while moving the mouse over links is 
Of course any highlighting is now gone ...

As far as I see now the highlighting of links itself is not the issue. What 
takes several
seconds is the display of a little popup window showing the contens of the link 
(e.g. "LINK: file:filename.org).

This must be a windows problem. In the past I already found two major 
performance hogs coming from
a display problem under windows:

- smooth-scolling.el
- hl-line-mode     - (add-hook 'org-agenda-mode-hook 'hl-line-mode)

Now I wonder if that little "LINK: " window can be switched off.
