Question Error message when running application (CT 7.20)

Hi all,

I just update my system to 7.20 version and I get the message error below;

"EInvalid operation updateForm [TCustomForm.SetFocus]" Of course updateform is a form from my application. It does not prevent the application to work properly after closing the error message box.

I checked my project and related parameters about the forms created in the application but I did not find any error.

Thank you in advance for help
