Glad I saw your post, I didn't even catch the 2693 one in Steve's post originally. I had seen the 4244 issue in an article in my Google feed already. Removed 2693 at lunch (hadn't seen any issues yet though) and set my update delay for routine updates to be 14 days up from 3 since that apparently wasn't long enough for the reports of problems to show up.
