Thanks for your answers.
Dan_C - Yes, I tried with the program already open behind any image, try to go to help> welcome screen, however when it opens the program closes again, I can not uncheck the box to not show the screen anymore. Even though I'm fast and click the box it does not accept the command because the program was already locked. I think if I could, it would work.
V_Kyr - As it was said, it is as if the programs were blocked to access the internet to download news, then they simply lock and shut, were working well, I do not know why this happens.
I do not have enough knowledge to modify the program log files to disable the welcome screen.
