"Drill Down" holes - are they working reliably?

One of the new features of 2009 was the ability to put a holethrough several parts in an assembly and have it "Drill down" toeach of the part files. Of course, it is a wonderful feature. But,with various the problems (some very serious) that are remainingwith even standard features in service pack 3 of 2009, I amhesitant to rely on an this brand new feature.

Anyone running into problems? Anyone using it extensively and knowit has been reliable?
