MS recently did an update that included changes to Explorer10 aka IE10

If you are having issues posting, return key non functional, other stupid stuff, try this:

on your address bar at the top right side, there is an icon that looks like a torn pc of paper....if kit is gray, click on it, and it will refresh your page, and allow the IE to run in a compatible mode.

Solved my issues here and a few other places.

Good luck!
