In the older Editors, we had a custom TextBox control that was used as the input area of the edit box. While that did allow some nice customization as far as being able to alter some input and inject other custom elements, it was a "heavy" design in general. We wanted to go with a more lightweight design that didn't use as much memory/resources when we rebuilt the newer Editors. The newer ones are based on the standard TextBox control as the primary input area of the edit box. With the newer design, as you commit a value (losing focus, pressing Enter, etc.), it should be using localized parsing to determine the number.
While I wouldn't expect a keyboard key's input text to be converted in the newer edit boxes, I would expect the resulting text value to convert to a number ok on commit. Do you see that happening, or is there even a problem with the commit conversion? If there is a problem, please tell us step-by-step what you see. Thanks!
