And even if it's true that bugs always tends to rise in all software, you should think that sometimes is better fighting against well-known bugs than against new bugs; for example, in critical-mission systems never are used newer versions of soft or hard, because you don't really know what kind of bugs you will find. In fact, upgrading depends on the scenario, the mission of system, the users, the money you have and also the compatibility with older versions! Saying that you should always upgrade your systems is a too-simplistic assortment (I hope this word is right!). Javier Polo.
