In my playing around with ML (and I'm excited!!) I found that my EOS M suddenly did not want to display the ML menus any more. When booted in M (manual) photo mode it used to display the ML menus when the screen is touched with two fingers. This has stopped for no reason at all - it just displays the "Welcome" screen ending with "Enjoy" So I could not change settings etc. I removed ML, restored the OEM EOS M 2.02, then camera formatted the SD card and re-installed ML.
Same response - only got the "Welcome" screen but no ML menu!!! Today after trying again, my hand slipped and I touched the SET dail's outer ring on the right side.... and MAGIC! There my EOS M came alive with the ML menus! I'm back in business!
I do not know if I posted in the right place or if this is even helpful to the forum members - it worked for me!
Regards.
