We encounter some issues with our web application made with Silverlight, while entering something in textboxes.

Default values for KeyHoldTime is 100 ms and for TimeBetweenKeypresses 10 ms  -  for our application I have to change every value to 350 + 100 to be sure the value is correctly entered.  It's time consuming to edit every textbox manually and it would be easier to have a project level setting for those.
