Hi Eric and Alan,
You can test your applications with the latest internal build (you can download it from your account pages at www.telerik.com). We recently fixed the issue from the following scenario: first minus key is pressed and then the value is typed.
As for the other "NOT" from the Eric's first post, Eric, could you please let us know the exact steps you perform in reproducing this because we are not able to see such behaviour in our demos or sample solutions. Thank you in advance.
