flobee: when renaming files in nb or committing code, nb rescanns all projects i think (some are uge but untouched). during a work day nb scanns nearly half of the day the code again an again. it feels like and in this time work is nearly impossible. 
somthing is wrong here! ... and after a day it takes a really long time to close nb. this is no fun anymore. if you nee futher information email "flobee" within an g mail account.
