ie 4 support

I have come up with the idea of creating a safe mode for ie4. this safe mode could be available for any user if they so desired. I know in the past some js has caused my machine to crash. a safe mode might be nice for some who have these problems. it may also be nice if another bug appears in a later version of ie this could quite possibly be a fast fix for some problems. in addition to this, it may encourage people to upgrade there ie. user notes will most likely not be available in ie 4 as almost all the current samples used the DOM. I believe the DOM is only supported by ie5, is it not? now, I haven't made a skin so I am not entirely sure but I think they need the DOM too. the safe mode may also be a quick fix for the user note problem. (however, not by any means a good one) safe mode may include.... - no user skin support - no customizable menu support - no user notes - anything else that may pop up. (or not pop at all) the entire idea of posting this was to fish for ideas.... any thoughts? Brendan
