In Microsoft Edge I have created a web for Google Messages that is pinned to the taskbar. When I open Messages I do not see any title bar buttons for DF, maybe they are hidden and I need to move them with compatibility?
I did look at the shortcut (C:\Users\xxxx\AppData\Local\Microsoft\Edge SxS\Application\msedge_proxy.exe) for what seems to be executing them but changing the offsets for this didn't seem to do anything.

Any ideas on how to get these to show?

Owen, so I go to create a screen shot today and the buttons are there now. I would swear that they have never been there!
I will keep an eye on them and let you know if they disappear again.

OK, Owen so I found what is going on.
On my WorkOffice computer buttons are showing. On my HomeOffice they are not. I attach 2 screen shots taken withing 1 minute of each other.
On both computers I set compatibility for MS Edge = -35 and 4 set for both min and max. I disable title bar and use vertical tabs. This is on Canary.
Not sure why it is working on one and not the other. Both are on beta 3.
WorkOffice is Dell desktop with 2 x Dell monitors at 1920x1200. On HomeOffice I have MS Surface Pro 4 on dock with same 2 monitors and Surface screen disabled.
On a third system, Surface Pro 3 with just the single built in screen, buttons show in all apps except the Edge Messages web app windows like the other Surface. Maybe an issue with the Surfaces; but why?

Owen, that fixed it.
Thanks.
