Periodically when browsing a table or viewing the results of a query, Internet Explorer 7 will fail with an operation aborted error. I'm not able to find a pattern that can cause this issue, as repeating the same query on the same data will often work without an error. The error is fairly rare and I generally see it about 1 in 100 attempts.
Web Server: Microsoft-IIS/7.0
Seen in phpMyAdmin 3.1.5 and 3.1.1
