Cannot add new components to form in designer when Timer present

[Chase Colvin]

When a timer has been added to a form, trying to add any other components afterward results in a type casting error. This continues until the timer is removed entirely, then new components added again. See attached screenshot of error.

The only workaround I have found is to completely remove timers when making any other edits, then add them back when done.
