Google Chrome GWT Dev插件不起作用 - 帮助

I have just downloaded the Newest Google Chrome to test my gwt app... And, of course, in first gwt app running chrome demanded GWT plugin to be installed. So I did... All great but when gwt test app starts it doesn't work as in eclipse Design - Preview or IE8 etc. Instead of panels activation chrome shows me just a blank right frame :( Moreover, since then my FF 5.0 GWT dev plugin started do the same (blank) tricks as if it was replaced with the chrome one :( I think chrome caused all these things... I have already uninstalled chrome but my FF still tricks me with (blank) things... So my question is...I have just downloaded the Newest Google Chrome
