It's simple! All you need to do is to rebuild index 
select on top menu Project -> show info
and rebuild Index



> Hi,

sorry if this is a stupid question: how does one move a project from one 
folder to antother? When I copy the folder and then try to build I get a 
build error: "buid failed... don't know how to make..."

When I try to use "File/Save a copy as" I get "Couldn't save the 
document". 
And that's got nothing to do with the write permissions - I did a chmod 
from 
the terminal.

I'm using WO5.1 on a MacOS10.1.4 Server.

Thanks in advance
