If you start a second project and enter no or less 
exclusions than in the first project, then the following 
happens:
The exclusions from the last project are shown before 
you start indexing the second project. At least it seems 
that this is just a display error, so the exclusions shown 
are not used for the actual project
!!! This bug only seems to occur on my installation on 
local host and not with the installation of phpcms on a 
webspace. !!!
Strange...
