Topic: Autotest reports test failures and the same tests pass on rerun

I am using Autotest 3.6.1 on Windows XP. It very often (but not always) reports some tests are failing incorrectly. When I save the file again (without any edits), it runs the failing tests and reports they passed!

Next time, when all the tests are run again, it again reports the same tests as failing and passes them when rerunning the failed tests!!

All the tests pass consistently when I run using rake test.

Has anyone seen this?
