BUGS: MarkupLabel IsMouseOver and Click Problems

I'm creating a control that allows the user to select a date using the mouse scroll wheel or by clicking. It looks like this:


By moving the mouse over the month, day or year columns and then scrolling the mouse wheel, that column will scroll the appropriate values in the column under the mouse. This is where bug number 1 occurs:

Bug #1) When using the IsMouseOver property of the MarkupGrid object, sometimes it returns TRUE even when the mouse is not over the object.

Unfortunately, I haven't yet determine when or why this is happening. To test, see my sample project and play around with the mouse wheel while moving around the MarkupLabel...eventually it should start scrolling 2 columns at the same time, even though the mouse is only over 1 column.

Next, the user can click one of the months, days or years in any row (except for the middle row) and the control will get updated to that month, day or year. This is where Bug #2 occurs:

Bug #2) When clicking a TextBlock that is a child of another object that shares the same mouse event, the event wont be raised again until you move the mouse. To test this, carefully click one of the month rows (not the middle one) WITHOUT MOVING THE MOUSE, and then click again. The first time, the month will change as expected, but the second time, the cursor will revert to an arrow and no events will be fired.

Here's the project for testing:
