This is the last test, on one in which a compatibility view settings change, as well as a trusted site settings change was made to my IE configuration. Thus far it appears to be working fine. Usually by the time I get to this point in the posting the letters start slowing down, letters get omitted, or I am unable to highlight entire words or backspace to correct the typing problems. The auto-save just came on so I'm now curious if that will start slowing things down, but so far it hasn't. I'm excited to finally find what appears to be the solution to the inability to post a message.
