When trying to close my form, I get the following message: Member object removed - cannot complete the Save operation

I fear that my SCX is corrupted. What can I do?

UPDATE: After closing and restarting VFP, I can see the button I tried to delete before getting the error. The problem is that VFP won't let me delete the button, it give me Cannot delete objects because some are members of a parent class. However, the button is not part of a parent class.

Other than making the button invisible, is there any way of getting rid of it?

UPDATE #2: Never mind. The button was indeed included in a parent class (not my code...)
