I've been wrestling with this for a day now. When trying to compile/make a class Intellij displays "Inspecting output directories..." and stays there for HOURS! I finally have to kill it. I've rebooted, deleted the cache, deleted the "paths to delete.dat" file as was suggested on a couple other threads I found to no avail. If I click on the background task I can see that it appears stuck on one directory and doesn't move.
I'm using 9.01
