Can't select anything on Facebook drop-down boxes?

[brenda]

I'm running Google Chrome and I can't select any options on any of the drop-down boxes that are provided by Facebook. For example, if I want to publish something to my wall but I want to change who can see it, I click the padlock next to the share button but I can't select any of the options on the list. I click on them but there's no response from the application. I can click the arrow button and close the drop-down box, but I can't select anything from the list. I also went into the account settings and tried several of the drop-down boxes there and I get the same result. None of them will allow me to make a selection. Is there a problem with Chrome? with Flash? with Facebook? ...help?
