In particular if you have two 24" monitors it couldn't be less annoying to always move the browser window and to resize it on startup. I know I could leave it open and ...

Regular Expressions and GWT
My questions is: Is there a good solution to use regular expression in GWT? I'm not satisfied with the use of String.split(regex) for example.
