Just clarify I'd like to know more about the environment you are using when you get this warning. Are you using hosted or web mode? What kind of system specs do you have? What specific browser are you using? Thanks.
Just to be sure I understand clearly, FNR means the fix will be in the next release version. The next release version at this point is GXT 3.0 and not necessarily the next release candidate? Do I have that right?
Also, I am guessing that SVN refers to the source code management system you are using?
No, in this case, with the release this afternoon of 3.0.0-rc2, most of the current FNRs will be changed to FIXED (see http://www.sencha.com/forum/showthre...-now-available for more details on rc2). Check the specific forum post for details as to whether or not any given issue is marked as fixed - we're reviewing them now.
And yes, we use Subversion internally to track changes to the library. As a support subscriber, you should have access to this if you wish to look at changes or to get the very latest code. Check your support page for details, or PM Brendan or myself.
Instead, compile your application to web mode, and test it that way - this will give you numbers that are consistent with what users will feel in production.
