I tried to add the date of a classmate passing from the date pick list and the scroll bar would not work. I had to go to IE11 to do the update.
Checking the forums there is an issue with the latest Chrome update 32 and no fix yet. See this forum link for more discussion:

This is not a Class Creator fix, but a Google Chrome browser fix. Use another browser for your date picks as an option.

Thanks John. This is good info. I just did a test with my Chrome 32 and it seems that as long as I scroll via my mouse wheel, it works. As soon as I try to use the slider, it fails.

You're right Scott. The scroll bar disappears but the wheel does work. Thanks.

Thanks Scott. Great, I can still use Chrome, but I have to learn a new way to scroll. I guess this old dog is still teachable. John
