There is some startup problem with newest version. It takes long time to start OMP after each N900 reboot: player is completely locked until number (count) of each file types appears (music, movies, internet radio). In stock player it`s instant, in older versions of OMP too but in the newest one it can take some seconds and I have a very small number of multimedia files on my phone.
Each consecutive OMP start is fine until next N900 reboot.
