Since #9 doesn't work I use it without Auto-Close, when using the Druid Teleport, the flyout is closed but then when I just press Escape it opens that Flyout (sometimes all others as well, one by one) before passing the escape to actually open the Game Menu

That issue is pretty new, so definitely last 1-2 updates

Thanks for the bug report!

I think this is the problem:

Sometimes, the Blizzard UI will close all open windows, including any open UFOs (i.e. flyouts). For example, open the map while a UFO is open. Another example ais teleporting to a new location ( casting Dreamwalk, a mage portal, walking into a dungeon).

When the above happens then the Escape key will mistakenly open those closed UFOs.

I'm working on a fix. Thanks again!
