Do you understand what beta means?
If the purpose was to "give a heads-up" to the FTMM software developers, this is not the appropriate forum.
This is a user forum and warning the mostly pedestrian users the program crashes when fired in a beta OS, months before its' release, is simply not warranted.
When ML is released (the buzz is this summer), it may or may not cause problems with a myriad of existing software applications. So goes the world of tech.
