I did some more testing and reverted to firmware v2.0.0-dev-12.14.
First of all I unloaded a lot of plugins that I recently installed and turned autoload off for those. I changed the buffer from 64 to 128 (still at 32K).
Morpheus is still problematic. I can get Morph to work OK.
I am noticing that the screen freezes are repeatable. They occur when sequences are playing at bootup and I go into the module display screen and try to turn the sequence off. The screen is frozen. Also, it freezes if I update a file via wifi when the module display screen is not loaded. When, I go into the display screen, the MM is totally locked.
