Hi everyone!
This is valyndira again...
Thanks to Phinds and Booogt for your responses, i've tried all your suggestion but they didn't work.
I'm thinking of put forms on this board so if someone wants to help me please try to start by double click on MainMenuPage, click on F1 button, F2 button, F3 button then click on Cancel button on Form3, it'll bring you back to MainMenuPage. Then try to start again with the same order and you will see that the Form2 won't be there.
Happy trying......
Thanks
