IE8 problems, and why I went back to IE7 ...
* was a major resource hog
* deleted most cookie files every session without any notice or option to control (all ones I store I deliberately want to keep - since they have preferences or login data I want stored)
* deleted all temp internet files automatically every session, with no ability to control (couldn't therefore get .mpg or .flv files of interest from there, or other files from there which are often useful)
In addition, it is clear to me that IE8 is mostly a marketing tool that adds no important new functionality. At installation, it tries to eliminate Google and other installed services and replace them with Microsoft services. It has some useless glitz factors like colored tabs ... like who the fk needs them? ... but, again, nothing particularly useful.
Maybe some of the problems have been fixed with patches? I don't know ... but I don't want to waste more time in attempting to find out.
