and backgroung scanning got stuck

GUEST: i do not understand why the IDE scan for external changes so often, and also de background scanning of projects, this should not be done in the middle of compilations or buildings, at least wait for the compilation to finish.
this 2 process of scanning looks to me like a dead lock

GUEST: Background Scanning of projects is never ending
7 projects in the projet view
size fairly std

GUEST: Started netbeans. Client started background scanning but it hangs and continues to run without progress.

GUEST: I was trying to edit two html files and a couple of javascript files. Continually interrupted by scanning of background projects and unable to type.

GUEST: I was trying to work. The IDE keeps performing background scanning of projects, and tying up resources and preventing me from working.

rgjacobsen: Trying to do a "Rename" refactoring, but class scan never completes

GUEST: <Please provide a description of the problem or the steps to reproduce>--

GUEST: Just run it on big project

GUEST: Unable to stop background scanning of project
