Steps to you see the problem:

1 - Create a Class (Form)
2 - Put 2 buttons: Save and Cancel
3 - In ThisForm.KeyPress: (Class)
If nKeyCode = -7 && F8
ThisForm.Save.Valid
EndIf
4 - In ThisForm.Save.Valid (Class)
MessageBox("Class - ThisForm.Save.Valid OK")
5 - Save the class...

6 - Create a form based in the class.
7 - Put a TextBox.
8 - In ThisForm.TextBox.Valid (Form)
MessageBox("Form - ThisForm.TextBox.Valid - OK")
9 - Save the file.

10 - Do form Sample1
11 - Click (mouse) on the button Save... Will appear 2 messages.
12 - But if you press the F8 key - Will appear just 1 message... The ThisForm.TextBox.Valid is not execute.

How can I solve this problem?
