Yes...
I made a utility which allows you to do this and I've tested it with my widescreen laptop (Inspiron 6000) and it's fine.
Either way, the simple way to do it is thus:
(taken from the SIBase article:
http://www.sigames.com/sibase.php?type=view&id=166)
Firstly, get your screen resolution. This can be easily done by right clicking on your desktop, selecting Properties, and then Settings.
This should bring up the current resolution. Mine is set to 1280x800 so we'll use that as an example.
Make a note of the settings and close the window.
Go to your desktop shortcut for Football Manager 2006. Right click it and select Properties again. This will bring up a window with stuff about the FM location.
You're interested in the box which is for the 'Target'. In my installation the value is this:
"C

Program Files\Sports Interactive\Football Manager 2006\fm.exe"
Now add the following values (change according to your screen resolution):
--fullscreen_width=1280 --fullscreen_height=800
The new target for me should look like this:
"C

Program Files\Sports Interactive\Football Manager 2006\fm.exe" --fullscreen_width=1280 --fullscreen_height=800
Click 'OK' and load up FM. This should work unless I've missed something out.
I created a command line editor specifically for problems like this and you can download it from:

Hope this helped.
