I tried that link in the help menu, but it simply goes to the following site: http://www.extjs.com/products/js/. It does not tell me what version is currently using! Can you tell me if the Build Version xds-22.214.171.124 is using ExtJS ver 3.2?
I see that sometimes the Designer says that a new version is available and it updates! Is this when the new ExtJS is uploaded? Maybe the about part should tell what version of ExtJS is using as suggested earlier! It would help a lot
