Great job Michael !

Yes, but it works.

Panning however causes problems for me:

- first the screen flashes very frequently while the map moves
- once the map is in its new position, I cannot use the mouse anymore, 
only my keyboard. However, when I change to another workspace of my 
Gnome desktop and then switch back again, the map display is empty, but 
I can use my mouse again.

Here they also cause a funny behaviour: when I chose import (or export), 
I get the command window (which is still the tcltk one, or ?) in modal 
mode, i.e. the other windows are dead. When I then click on 'close' in 
the command window, it closes and then reopens immediately. When I close 
it a second time it closes and the other windows (gis manager and map 
display) become active again...

My tests are on Debian testing/unstable.

Even though my programming knowledge is limited (just as - obviously - 
my time), I am willing to help with this, at least in the form of 
testing, but maybe even some simple coding.

How about [[Media:FileName]] ?
