Cor, Well, I did suggest the TextField/Scrollbar thing before. Then I followed up with my extend TextArea thing (then Muzak one-upped me.) In terms of reusability I think it is a greater hassle to have to configure a TextField/Scrollbar solution than to go the extended TextArea route.
The code is already written, where's the hassle? Muzak, > So it's not really a bug, just a (very) bad decision. How is 'a (very) bad decision' not a bug when it impacts functionality like this?
