Okay, wtaf, #Microsoft:

Was just doing a demo, & #Teams has added this new "feature" where, if you're sharing the screen, anytime you hover on the taskbar to access one of the bazillion windows I have open, there's now a new (as of this week, I think) "Share" button at the bottom of each thumbnail—which absolutely thwarts actually clicking on the window you want to bring forward.

Like....HOW IS THIS HELPFUL????
