The UI is having that problem again of when clicking through the UI quickly (though not abnormally quickly), the UI gets into a state where the tabs keep switching back and forth. See the attached video (in .ogg format) as the example that I just witnessed.

I failed to reproduce. Can anyone get this to happen with fairly standard repro steps? There has been one tabbing fix since this was reported. Probably not going to stop this but it's possible, as it did prevent an unexpected smartgwt event from getting generated in certain situations.
I replicated this by fast clicking for a couple of minutes. I was on a resource view (with the tree on the left and tabbed view on the right) - then, just start fast clicking. I had no method to my madness - I just clicked as fast as I could on all tree nodes and all tabs - going back and forth between clicking tabs and tree nodes.
