hi!!
i managed to start it, but i have a problem. i don' t know how to open a task. any help?

You don't open tasks using BookMan, you switch to them. Selecting another window makes your current window "minimise".

BookMan only allows you to multi-task by allowing you to "minimise" certain windows and opening new ones. Don't do more than your phone can handle or it will restart by itself.

how to switch it?
in the file that I've uploaded, there is a select between the process,but then again, it doesn't minimize the window to another...

Don't quite get you. From what I understand, it just brings the window you selected forward. What's the thing you want to achieve? I'll tell you if BookMan can accede to your request.

i got it now. i forgot to update my dyn_const.bin files.

this thread can be closed.
