Strange problem exhibited only with IE10 on Windows 8. No other IE version, no other OS version.
Some stylesheets are aborted, apparently in transport, intermittently.
This seems to happen when there are three
<link> tags in sequence. The tags are correctly specified and are being served from Amazon S3 over HTTPS. The first two items abort when (or prior to) loading. Altering the order of the items appears to make the first two items abort in all cases.
This problem is intermittent, and different people can reproduce with differing success.
I have seen a lot of conjecture about this on the web but no solution.
