Chrome started misbehaving badly on my SP3 last week. I have the 64-bit v. 39 (I think...don't have the Surface nearby at the moment). The primary window started disappearing after starting up. I have it set as default browser, running in Modern mode, and it starts, shows the red screen for a moment, then disappears, leaving several running processes behind. I've tried restarting, deleting and reinstalling, etc. to no avail. It runs fine in desktop mode. The new IE is much better than any version that has come before, but Chrome is still my main browser. Any thoughts or similar behavior? Edited to add: This is only happening with Chrome, not other MUI apps, though a couple of times I've seen MUI apps (Microsoft Solitaire, for sure) slow almost to a halt and suddenly decide to come back to life and catch up to themselves minutes later. Since writing this I see a few people saying updates are causing MUI apps to fail. I'll try going back in time an update or two when I get home tonight to see if Chrome behaves any better.
