userform when called doesn't show scrollbars

I have a userform dialog box that is called by a form button. The user form contains a textbox in which i've pasted about 5 pages worth of text into. When i call the userform the vertical scrollbars (enabled in textbox properties), do not show until I click within the text box area and then the text view is the very last portion of the text with the scrollbar then showing up but it having been auto dragged to it's lowest position.
1. how do i get the scrollbar and text to display correctly when i first call the userform?
2. bonus question... how do I prevent an end user from being able to edit the text?
