From http://community.sharpdevelop.net/forums/t/9182.aspx:

I think it may be that the #D doesn't realise that the drive letter
for project can change, even though it's may be on the same drive that
#D is running on

@ Home my flash drive comes up as 'U':, while @ work it comes up as
'D:'.

The project is also stored on the Flashdrive in folder
'{root}\Project\Project1'

If I work @ home on the project, compile etc - then go into work &
start up #D - the project doesn't show up on the start screen -

If I 'Open' project [...] then close/open #D again - my project now
appears on the start screen. [...]

BUT when I get home & start up #D  ... My project doesn't show up on
Start screen (again), just like in work. If I do exactly the same
thing as I did in work... the project reappears on the start screen &
just like it did in work ...

If SharpDevelop is installed on a removable drive, recent file and
project paths should be stored relative to the installation directory so
that settings move with SharpDevelop as expected.

Also, we should identify other options that store absolute file paths
(view content mementos?) and adjust them accordingly.
