these problems were already faced while developing the TAR thing, i don't understand why they are here again.
i can't even investigate because i don't have sources of past 2.1 betas.
i'm very disturbed such important problems reached the stable versions. we had so many months testing.
anyway, i reviewed the listing permissions. i hope this build 053 to be ok.
but please, test it yourself, ASAP, because i'm not home this week and can't test it thoroughly myself.
