About a week ago or so, Internet Explorer 10 decided that it won't allow me to download anything. All download links just bounce real quick when clicked. Nothing else happens. No downloads dialog, no download popup, nothing.
So far (besides the usual reboot), I've checked the Temporary Internet Files (the only Google references I found that were even close to my symptoms had that as a solution) and temp paths to make sure they make sense. I've also cleared the cache. No change.
What else should I try?
