Ever encounter a bug where UI buttons are not clickable or elements are mysteriously missing?
This is usually caused by a bug in the Blizzard frame code, whereby child frames can accidentally be assigned a lower level in the frame strata than their parent, leading to buttons that appear "behind" their container, making them either unclickable or completely hidden.
StrataFix provides a simple workaround for this bug, which affects numerous UI elements, notably including:
many AceGUI addons
Just install as usual and it silently does its job, problem forever fixed!
