1-openmediaplayer-99fa336: OMP icon clicked -> 3 seconds -> main menu visible with song count and immediately usable
2-openmediaplayer-afd396a: OMP icon clicked -> 3 seconds -> main menu visible but locked and without song count -> 18 seconds -> song count appears and GUI unlocks
openmediaplayer-test: OMP icon clicked -> 3 seconds -> main menu visible but locked and without song count -> 18 seconds -> song count appears and GUI unlocks
openmediaplayer-test2: OMP icon clicked -> 2 seconds -> main menu visible but locked and without song count -> 18 seconds -> song count appears and GUI unlocks

As you can see it`s VERY consistent behaviour: all binarys (except 1-openmediaplayer-99fa336) are locked exactly the same way. openmediaplayer-test2 starts slightly faster but its locked state remains the same.
