I've actually had this issue since M1, thought it was fixed in M2 until recently.
Can't figure out why, but randomly on certain projects intentions and inspection just stops working. In the past rebuilding the IDEA project file (using maven idea:idea) seemed to fix the issue, but as of M2 that no longer works.
Mac OS X 10.4.10 with IDEA 7.0 M2.
Anyone had this issue? Know of any workarounds/fixes?
