Attaching network files in thunderbird..

[WipeOut]

Hi,

I am new to Ubuntu (coming over from Fedora) and so far I am very 
impressed.. Just about everything "just works".. I am using Feisty and 
its been perfect for the last week I have used it..

Something I haven't worked out is how to attach network files to emails 
in Thunberbird..

I have setup a couple of network "places" and these show as icons under 
the places menu and on the desktop.. In OpenOffice when I go to open a 
file these same icon appear in the browser window on the left so I can 
navigate to network files and work on them.. When I try and attach a 
file to an email in Thunderbird the same browser window appears but the 
network places are not shown so I can't access the network files.. Is 
there some way to make these show up or am I going to have to go back to 
the old way of doing things and mount the network shares into the 
filesystem rather than using the "places" menu?

Thanks in advance..
