I thought it was my computer, but now I see it must be the site. I had the same issue where I went to change a misspelled word and it locked me out. I could not type anything or move the cursor at all.
Jeff, I think Andy is working on things now so there may be an issue here and there with how the site works. There's no other way to do this than to just do it. Errors/issues will be encountered. They will be fixed ASAP I'm sure.
