I noticed since the last update that, and this has been an issue for me in the past, that I cannot add any of the "smilies" to my posts.

Also, I used to be able to shrink/minimize a section I was not interested in, Electrical for example, by clicking on something in that sections header bar. That is no longer an option, there is only an arrow that takes me back to the top.

All updates have been applied and no changes to anything else on my computer. I am on Firefox and XP if that makes a difference.
