Optimal browser to use with Zoho creator?

Optimal browser to use with Zoho creator?

Hi, I am trying to develop an events database for my organization with creator. i have been using firefox but most of our staff have Mac OS X and are using Safari. Is there a setting I can change to make it more compatible with Safari? Right now when I try to change tabs while using Safari it tells me I'm not authorized to access my second tab. Also none of the buttons seem to work in Safari.

Firefox has been working better but i just noticed it seems to have a bug in the "plus" button in the calendar view as well. It comes up with a weird screen that looks all fractured.

Is there anything I can do for my staff who are all using Safari (and our IT dept won't let them all switch to something else) to be able to fully access the database I have made? Or, is this really only fully compatible with IE or something?

Can you help?
