I am having the same "slow" problem on win 2k, but not on win xp. I reverted to version 1.41 on the win 2k machine, and it works fine once again. I will keep using 1.41 until a newer 2.0 version is available, at which time I will try that.
Note: the cleaning is up to 10 times slower with the new version on the win 2k machine. For example, approximately the same number of megs may take approx 20 sec with the new version, but only about 2 seconds with 1.41.
