two more snapshots on the slowness reported with this bug.
A couple of observations:
--After the period of complete unresponsiveness the IDE returns to normal responses.
--The slowness starts when clicking on a file to open it in the editor. Scrolling etc. does not trigger it.
--The projects open in NB at that time contain over 1000 files.
--Slowness only started to be cumbersome after some time (>2h) of using the IDE.

No any update? Is there somebody working on this? This is really a big issue now, I have to restart NetBeans many time every day.

Right click in Projects area sometimes freeze the IDE. Using Metal Look And Feel cannot reproduce this problem, may a MAC skin bug.
