Andrus,
There is no problem registering the control in the form's Load event. I have one question however, why? You can add code anywhere in the application to register the control. You could do this during the initial launching of your application. The code could also check the registry for the particular entry in the HKEY_CLASSES_ROOT section and if it doesn't exist, register the control.

It just seems overkill to do it every time they enter the form.

Just my $0.02 USD.
