Hmmm i am on 3.2.2 here tested in FF 3.6._current and Chrome 7.0 on Windows 7 Ultimate.
To test i simple replaced the onReady call of my real app with the code from my post above.
And i can not for the Life of me replicate the issue, in no Browser.
I hit the Refresh button in Chrome with and without Ctrl for like 20 times.
Your best bet would probably be to try without your custom CSS you might have and quadruple checking if no Extensions / overrides / custom components are interfering.
At first I was disappointed in your reply, because I'm not using any custom CSS. But then it got me thinking and I figured it out!
Sorry for the stupidity all, and thanks for all the help!
