I have a working fullcalendar on my site, however, the actual calendar table doesn't show until you change the month/year or select "today".
If I look at the rendered source, I see that the div around the table is empty until I press a button.
<div style="position: absolute; -moz-user-select: none;" class="fc-view fc-view-month fc-grid" unselectable="on"></div>
Does anyone have a clue why this is happening?
