it seems that the RSS filter manager somehow continues to refreshed it self, don't know why this is happening, the only thing thats helps is to uninstall Download center and install it again.
It happened twice now and it's a pain to setup the 20-some filters again.
I allso fund out that it slows the NAS a lot. and sometimes makes it disconnect the login session.
Do any one else have this problem ? and maybe someone have a fix?
