We use Google Apps and Google Sites at Miraloma Cooperative Nursery School.
Currently, some users of Safari cannot correctly see all of the events from our school calendar in the Google Sites calendar widget. We have also seen this problem in Safari on an iPhone and an iPod Touch.
Here are some screen shots that show the problem.
