Hello, kqdelphi:
I’m from Spain. Sorry, I still can’t understand your question.
Are you saying a custom component sometimes is displayed and some not?
At runtime or design time?
If yes, it not happends for me.
What happened to me sometimes is, when there is a error in a custom component, all the other components displaying (custom or not) may dissapear or display ERROR. Then the only solution is repair the error.
Regards,
Vicente
