--- Comment #6 from gjin@ubicom.com 2010-03-31 17:07:46 --- Tested on 1.1.39 and problem still presents, but little bit less serious because the working around described below can make things to work.
Multiple click will bring down the pull-down menu. For text field, multiple click does not work well, but clicking on a neighbor field then quickly move toward target text field and then click on the text field will activate the text field.
