Quote from NevcairielAnyone that could reliably reproduce the MicroMenu Bar problem, please get the latest Alpha version from WoWAce, and see if it still happens.
Sadly i could not reproduce the issue no matter what i tried, so i tried rearranging the code that moves/shows the buttons a bit.
SUCCESS!!! Whatever you did has fixed my problem with the Micro Menu - it no longer disappears.
Many thanks for a great addon and great response to our pleas!
