I down loaded IE7 the other day I was very annoyed that it wiped out IE6 on install, as its a beta it sould not do that IMHO but allow you to run both.
I dont use IE very often I prefere firefox, but do use it for sites that wont work on anything else, also some video streams wont work on firefox but do on IE.
Only probs so far is it sometimes fails to realise I use a router and wants to know what connection to use but doesn't give one any choices
totally stupid.
