Hi Marcos, i have been using the thread library for a while and i haven't had any issues with it so far, the reason i started using it is because i made an app for a client that required creating a pdf workbook of more than 300 pages, as you can imagine this process takes a long time to complete depending on the amount of information each pdf page contains, if I left the application run without any type of background task handling then the user would just keep tapping on the screen now knowing whether the application crashed, then the OS would keep popping up the message saying wait or close application.
I know Erel doesn't recommend using this library and I understand his reasoning behind it, but i personally have not had any issues with it, the only downside of it is that you won't be able to run your up in debug mode.
Regards,
Walter
