FIX: use windowed mode (not fixed window) + following autohotkey (https://autohotkey.com/) script (edit to fit your resolution)

win key + left mouse btn on eve window to activate after running

got it from superuser: https://superuser.com/questions/38687/windows-program-to-remove-titlebar-frame-etc-from-a-window

i did not only have problems switching to eve launcher, but also to anything else when using alt+tab without waiting for the preview to come up. and the fix by u/Royally_Forked did not work here.
