Set focus to another field before clicking OK. a bug was introduced into many of our interfaces associated with the CS4 updates we made... now the last field you update may not register unless you click into another field in the interface. It used to work that the button click would act as that next field, but in the new UI it doesn't work quite the same. We will be updating our products to address this issue, but it is relatively easy to work around once you know what to look for.
