Not for me. I did not have that problem before the update, and did encounter it on one machine today.the 15.15.0 Update has fixed the most common error I had, which was Excel doing the "bounce, bounce" in the dock and then crashing on startup. Now it is working OK again.
Found a new to me problem: One of the features I really like about OSX over Windows is the ability to change a filename in Finder while the file is open in the app. But today I made the mistake of trying that with a PowerPoint file. The filename did not change in PowerPoint as it always has in the past, and I ended up with a munged presentation that I had to rebuild. Something going on with file management comms between MS Office apps and OSX methinks, but then I am not a modern day programmer.
