Can you still reproduce this bug?

I can still reproduce this bug. I don't exactly know what I'm supposed to see, but I'd bet my bottom dollar it doesn't involve clicking on the Stacks applet to restart it. Not sure what video card. It's a T41 laptop, stock hardware. Also not sure how to get backtrace if it applies.
