A shortcut for dropdown menus is the down-arrow button. Try pressing that to select your word.

Thanks for the suggestion, but it did me no good :-(

I'm having this same problem in basics 2... the drop down menu comes up but there are no options except "select word"

And today, there is a different drop downmenu problem -- in the first lesson in "food", four separate drop down menus haveprovided only incorrect answers

they also don't show a correction in spanish, only english, so you never find out what the correct answer is.
