new task button does not work

on the zBIZ front page:

1. creating a new event works.
but cannot open existing events, i by click, or double-click,or popup menu.
how is it supposed to work?

all results in spinning ball, actually the 20yr old mac watch here.

2. new task does not work.
results in spinning ball/watch.

then i go to the task page. - >new task, same results. (new task button)
HOWEVER, if i type directly into your beautiful "click here to add new task" field, then it works fine. but most people will overlook that and go for the button, until they learn.

restart browser, same results.
