Scheduler neither saving nor updating events in IE9

I’ve noticed that, when using IE9, the scheduler is acting strangely.
When I add / edit an event and refresh the page subsequently, the newly added events are not showed. But if I restart the browser (or visit the scheduler with any other [decent] browser) I can see the events I’ve just created / modified.

Is this a known bug? Or merely a problem of mine?
