I want A4 as I can't trust A3 while making missions. All the reasons can be read in the development branch so no need for me to open up that discussion here. All other versions I gladly updated to because they were better looking and had more features, this time I want to change so I can leave A3 behind. Sad to say.
we can't help you if we don't know what you're trying to do and if you don't provide the code of your functions (omtk_xxxxxx).
By the way a while / do without a sleep inside is not a good idea most of the time.
And exitWith will stop your script before the end, i don't know if it's what you want.
