A few problems I've been having, please excuse me if I'm missing something and they're not bugs.
1) If I right click a date to add a Task, it will open the Task window set to add a Task to today's date, not the date I right clicked on.
Adding Events works as I expected - adds an Event to the date right clicked on.
2) In the New Event and New Task windows, the Start Time and End Time date formats are always mm/dd/yyyy regardless of what the date format is set to.
3) I have the calendar position set to On Desktop. When I try to move it around, the image of the calendar jumps to the right of the screen (as opposed to staying under the mouse cursor). After releasing the mouse button it's impossible to click on the calendar - both where the image is and where the cursor was released. I'd have to kill the process then relaunch it upon which the calendar appears where the cursor was released, not where the image had jumped.
