Just a quick announcement—there was a forum configuration change that occurred around a year ago that flipped several of our older bug reports to an Under Review status even though we had already acknowledged and reported the issues. Because there were so many that were affected, we simply left them alone and continued to work the newly-reported issues. However, we've recently been doing some maintenance and decided to mark all of these old reports as Acknowledged as part of that clean-up. Doing this triggered some people to be notified of the status change, and probably raised questions about whether we're taking new action on these old issues. All of these old issues have already been reviewed and reported, so we aren't re-reporting any of these old issues.
Of course, this does not necessarily mean that they've all been addressed. If you had reported something over a year ago that was recently acknowledged and it's still a problem, please make a new bug report and we'll investigate. Make sure to review our Bug Reports FAQ to ensure you're getting the right info to us in your report. Thanks!
