I have about 50 classes and triggers with only 6 of them < 100%. My code coverage is almost always around 90%. I compiled, re-ran tests via the Apex Test Execution page, and then estimated my org's code coverage and it comes out to 65% now. As you can see from the pic, all classes and triggers listed are in order by code coverage % asc.
I'm hoping that I'm just overlooking something simple here. Why would my coverage drop so much, yet show that most all at 100% or 80% and higher?
