When I vote on a question or answer and then quickly (within 1-1.5 seconds) switch pages, I often receive "An Error Has Occurred, Please Retry Your Request". If I revisit the page, sometimes my vote shows up, other times it doesn't. This error is hard to reproduce and because I'm always navigating away from the pages I'm not able to inspect the code of the popover box, which I've read here (on meta) contains error information.
I'm using Mac OS Lion and Mac mini with Google Chrome.
Is this a known issue or browser/OS specific problem?
