[Plugin: Event Calendar / Scheduler] Functionality problems

This event scheduler shows a lot of potential but I am experiencing some major problems. I have version 2.0 of this tool installed under WordPress 3.0 and it doesn’t show Events in the Events Adminstration panel nor in the Calendar after adding and clicking “Save Changes”. Yet, the “Number of Events in widget” field shows 2. So, how would I edit or delete an existing Event other then going directly to MySQL?

There is a problem in the Settings panel. After modifying settings and clicking the “Save Changes” button it appears to be refreshing the panel but it always brings up prior settings.

There is also a problem with navigation. If I bring up the Scheduler web page to view the calendar and press the back button in IE 7.0, it requires 2 clicks to get back to the previous web page.
