I could never reproduce this with 2.0.1 but maybe 2.0.3 works better. I will optimistically close this as fixed but if 2.0.3 still fails for you just reopen.
(In reply to Mr. Bones. from comment #2) > if 2.0.3 still fails for you just reopen. I tested it again and it worked fine. It seems the bug is gone. Thanks.
