i use the website, and it seems to happen in multiline text fields. I'm also using Google Chrome. I'll keep a better eye on when it happens.
Actually it just happened when I was typing the sentence above and the first "e" in eye disappeared, when I went to take a screen shot it was there correctly. It's definitely something to do with the word wrap. If you need more info, I'm sure you will this probably doesn't help much. I'll try too take a screen grab vid.
i'll try it today, i just typed out a reply to another topic, and had a weird ctrl+z occur. Something is definitely up with this. I refuse to use IE, but I'll give Firefox a try, and for you I'll open IE. ;-)
