I have been using automatic template updates (via hooks) for the last 18 months ( my Members Who Visited Today was the first mod of mine to use it in Oct 2005). In all that time I could almost count the number of problems with custom styles on my fingers - it's simply not a common problem. Even so, soon after I converted my mods to vb 3.6 I started adding the option in them to disable the automatic updates if you preferred (and also to edit the string they searched for).
