how do I enable access to other word documents while a form is open?

Hi,
I'm developping a word wizard with a number of textboxes a user is expected to fill in. It so happens that most of the texta user would fill can be copied from another word document.

Therefore, ideally, I would like the user to be able to switch to the word document, copy the desired text, switch back to the wizard and paste the text into the appropriate textbox.

However word disables access to all other open word documents while a form is open, hence preventing the user from copying any text.

Is there any way to get round this and allow access to other word documents even while a form is open?

Thanks to anyone who can help!
