Every single application or popup window will always attempt to get the highest z-order and switch keyboard input focus from wherever you were working to this window.
More than once, this resulted in input into the wrong window, causing problems.
And running this piece of junk os in a triple monitor setup; why do new windows (mainly outlook related) open on a different monitor ? If my input is on monitor 2, why are new windows opened on monitor 1 or 2?
A straight forward install of a recent Ubuntu version is much friendly for the user. But, as stated by someone else, improving the product is not gaining any cash flow.
Blink the window-title and in case something like a taskbar is used, use the application icon to get attention.
But don't act like you are the most important and single application on the system. Be modest.
