Enter does not work

This is a minor problem, but in typing in any forum, this and others, with Win 8, my Enter key does not move the cursor to the next line,

like this (entering this from Win 7) it does not seem to do anything. This is irritating because it does not allow me to add paragraph breaks, breaks around uploaded screen shots, etc. Does anyone have a fix and/or workaround for this? Thanks.

Seems to be unique to IE10, I've installed Firefox and it doesn't seem to have the same issue. I guess the IE10 version in Win8 is not all together ready for prime time either.

Thanks for the reply Randy. Perhaps I will try with Chrome (I really do not like FF at this time)

edit: It works in Google Chrome as well. Thanks for the advice. I realize that IE 10 is also a very early version, and definitely not ready for prime time.
