I finally cleared my browser cashe yesterday. Twice when trying to log in, an error message came up, but on the third attempt I was successful. I still have some of the glitches you were talking about. One of them is the editor below as I write this. There are all these boxes with no pics in them. If I hover the mouse pointer over them the description will show but no symbols, like ordered list,indent, insert/edit link, horizontal rule, emoticons, etc...
Also with the emoticons, when I click on it, the page loads but without the pics of the emoticons, and again, when I hover over each one, a description appears.
Nothing major, just pointing them out..
