Change Form size of MUI_WELCOMEPAGE

Hey folks,

I had to change the MUI_WELCOMEPAGE_TEXT for a special installation. Thus, the new welcome text is to long and could not completely displayed in the form. Is there a approach to change the size of the form or a property for a autoscale of the form ?!

I already used the search function but have not found something.

thanks

Are you using the 3LINES define?
